New improved selection code: - Selection decopuled into a new class - When you drag the selection against the limits it won't become permanently smaller, it will "bounce" trying to recover its size. If you drop it again it will adapt its size to the borders of the screen. - Fixed bugs in the button position algorithm. - Implemented selection animations for future implementations.
