Work on major sub-task EXT-991 (Update bottom bar behavior on resize)

Implemented functionality to process Buttons hidden/shown via context menu
1. hidden buttons are not processed while resizing
2. setTrayButtonVisibleIfPossible() is implemented:
	 * If it is impossible to show required button via context menu due to there is no enough room in bottom tray
	 * it will no be shown.
	 * Method also stores resize state to be processed while future bottom tray extending:
	 *  - if hidden while resizing button should be hidden it will not be shown while extending;
	 *  - if hidden via context menu button should be shown but there is no enough room for now
	 *    it will be shown while extending.
