Refactor dispatch_cursor_button
There was a separate function dispatch_cursor_button_floating which dealt with the resize and move operations, but as resize is not really limited to floating views, it doesn't make as much sense to have this separate. So both functions are now combined into one. Additionally, dispatch_cursor_button now uses a pattern of returning early instead of using else-ifs.
