Selection modes (#798)

* Fix a typo

this is required because this is "Paint" Selection
(so it's not supposed to cancel selection if we click outside the canvas)

* Added Selction Modes

Default, Add, Subtract, Intersect

* removed whitespace

* better options

* Removed Separators from headers

* formatting

* more formatting that i didnt notice

* Solved Shortcut conflict

* remove whitespace
