v0.4.2.2

* (Add) Shortcut "ESC" under Islands list view to deselect all items
* (Add) Shortcut "CTRL+A" under Islands list view to select all items
* (Add) Shortcut "*" under Islands list view to invert selection
* (Add) Shortcut "CTRL+F" to go to a layer number
* (Change) Layer image is now a RGB image for better manipulation and draws
* (Change) Layer difference now shows previous and next layers (only pixels not present on current layer) were previous are pink and next are cyan, if a pixel are present in both layers a red pixel will be painted.
* (Fix) Save modified layers on .cbddlp and .cbt corrupts the file to print when Anti-Aliasing is used (> 1)
