* When moving window into zones using arrow keys, support multi-monitor scenario

* Minor coding style adjustments

* Split implementation into separate functions because of readability

* Rename certain arguments

* Modify unit tests after API changes

* Address PR comments and add unit tests

* Return true from MoveWindowIntoZoneByDirection only if window is successfully added to new zone

* Improved monitor ordering (#1)

* Implemented improved monitor ordering v1

* Fixed some embarrassing bugs, added some tests

* Added one more test

* Extracted a value to a variable

* ASCII art in unit test comments describing monitor layouts

* Removed empty line for consistency

* Update comment to match the code
