[ColorPicker]Custom color formats (#22141)

* [ColorPicker] Development: custom color formats, first steps

* ColorPicker development of custom format handling.

* Custom color format developmnet.
Added common helper class for format string
Fixed settings loading
Added numbering if default name exists   (My format (1))

* Custom color format implementation.
Extended the colorPicker settings with the format string
Updated the color to string conversion

* Custom color format in color picker, development.
Adding edit, delete buttons. Implement functionality
Re-arranging settings panel (newly created formats at the top)
Implementing details (valid parameters, more format elements, more types)

* Minor commit

* Development color picker custom formats. "Last" steps.
Replacing hard coded english strings with resources, polishing.

* Adding help to the format edit dialog.

* Undoing changes unwillingly commited in Host module

* Fixing bug unable to delete a custom format after renaming it - use the colorformat object as reference (and not the name)
Modifying the default custom formula
Removing unnecessary using directives

* Udating the default user defined color format

* Removing unnecessary using directive

* ColorPicker Implementing custom color formats: adding custom formats to the default format selection (dropdown box).

* Fix binding of name and example

* Custom color formats, implemented steps:
vorwarts compatibility loading settings.
Fixed UI as requested (removed one settings panel, added button to the first panel)

* Minor change in the UI: description modified

* ColorPicker Custom Color Formats develepoment.
Added conversion from old predefined formats to customizable formats.
Extended default settings (in case settings file is deleted/corrupted).
Minor fixes.

* Fixing color format parameters.
Implementing 3 different Saturation calculations, 2 Hue calculations and 2 Lightness calculations (depending color format)

* Color Picker: New/Edit Color format. Fixing bug when cancelling addition/edit

* ColorPicker. Updating help section, available parameters

* Fix spellchecker

* Remove the MinWidth so that scrollviewers can be drawn

* ColorPicker bugfix: Not allowing to delete the last color format.

+    Microsoft ResX Schema 
+    
+    Version 2.0
+    
+    The primary goals of this format is to allow a simple XML format 
+    that is mostly human readable. The generation and parsing of the 
+    various data types are done through the TypeConverter classes 
+    associated with the data types.
+    
+    Example:
+    
+    ... ado.net/XML headers & schema ...
+    <resheader name="resmimetype">text/microsoft-resx</resheader>
+    <resheader name="version">2.0</resheader>
+    <resheader name="reader">System.Resources.ResXResourceReader, System.Windows.Forms, ...</resheader>
+    <resheader name="writer">System.Resources.ResXResourceWriter, System.Windows.Forms, ...</resheader>
+    <data name="Name1"><value>this is my long string</value><comment>this is a comment</comment></data>
+    <data name="Color1" type="System.Drawing.Color, System.Drawing">Blue</data>
+    <data name="Bitmap1" mimetype="application/x-microsoft.net.object.binary.base64">
+        <value>[base64 mime encoded serialized .NET Framework object]</value>
+    </data>
+    <data name="Icon1" type="System.Drawing.Icon, System.Drawing" mimetype="application/x-microsoft.net.object.bytearray.base64">
+        <value>[base64 mime encoded string representing a byte array form of the .NET Framework object]</value>
+        <comment>This is a comment</comment>
+    </data>
+                
+    There are any number of "resheader" rows that contain simple 
+    name/value pairs.
+    
+    Each data row contains a name, and value. The row also contains a 
+    type or mimetype. Type corresponds to a .NET class that support 
+    text/value conversion through the TypeConverter architecture. 
+    Classes that don't support this are serialized and stored with the 
+    mimetype set.
+    
+    The mimetype is used for serialized objects, and tells the 
+    ResXResourceReader how to depersist the object. This is currently not 
+    extensible. For a given mimetype the value must be set accordingly:
+    
+    Note - application/x-microsoft.net.object.binary.base64 is the format 
+    that the ResXResourceWriter will generate, however the reader can 
+    read any of the formats listed below.
+    
+    mimetype: application/x-microsoft.net.object.binary.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Binary.BinaryFormatter
+            : and then encoded with base64 encoding.
+    
+    mimetype: application/x-microsoft.net.object.soap.base64
+    value   : The object must be serialized with 
+            : System.Runtime.Serialization.Formatters.Soap.SoapFormatter
+            : and then encoded with base64 encoding.
+
+    mimetype: application/x-microsoft.net.object.bytearray.base64
+    value   : The object must be serialized into a byte array 
+            : using a System.ComponentModel.TypeConverter
+            : and then encoded with base64 encoding.
