Fix Window ScreenShot (#314)

- Removed ScreenShot Transforms in favour of Image Editor
  Corresponding Settings, Localisations and UI removed.


- Fix Window Rectangle finding code.
- New option in ScreenShot settings: `Window ScreenShot Transparency` to specify whether window screenshots should be transparent.
- Mouse Cursor included in Window ScreenShot only if within window bounds.
- Capture Window Transparent region inflation reduced from 100px to 20px.
- Refactor code into a `WindowScreenShotBackdrop` class.


- Other Fixes:
  - `CustomSize` used instead of `CustomUrl` on `FFmpegPage`
  - `MouseRightClickColor` used instead of `MouseMiddleClickColor` on `MouseOverlayPage`
