## Summary of the Pull Request
This PR removes the ISettingsUtils and ISettingsPath interfaces to
reduce some complexity. They only existed so the classes can be used
with moq. But this is also possible by using virtual methods which is
cleaner.

## Summary of the Pull Request
SettingsUtils is initialized multiple times over the whole solution.
This creates one singeltone instance (with the default settings), so it
only has to be initialized once (and improve performance a bit with
that)

## Detailed Description of the Pull Request / Additional comments

Adds option to choose from 3 click behaviors for each standard mouse
button:
* **Pick color and open editor**: Copies color to clipboard, saves it to
the color history and opens the editor
* **Pick color and close**: Copies color to clipboard, saves it to the
color history and exits
* **Close**: Closes color picker without copying the color
Pressing <kbd>Enter</kbd> or <kbd>Space</kbd> does what clicking the
primary button would.
Left and middle click actions execute on mouse down, right click on
mouse up for reasons discussed previously (I can't find the conversation
now)
Default settings are chosen in such a way that very little or nothing
changes by updating.
