Paulo Faustino 8e4b806419 More accessible screen layout settings. (#3340) 
* Remove borders from status bar items

On Ubuntu the status bar didn't look as good as on Windows due to some border being drawn around each status bar cell.

* Revert "Remove borders from status bar items"

This reverts commit 15fd32bf2b33d72f5c1b589b35c8dd6232ad263c.

* Remove borders from status bar items 

On Ubuntu the status bar didn't look as good as on Windows due to some border being drawn around each status bar cell.

* More accessible screen layout settings.

Depending on the game I'm playing I find myself needing to switch screen layouts very often and it's currently a hassle to have to open the settings dialog in order to do that so I've added shortcuts for the screen layout options and swap screen option on the main menu plus I added a keyboard shortcut to quickly toggle between the available layouts during game play (F10). I've also updated the swap screen shortcut (F9 now, used to be Ctrl + Tab) so it's next to the layout toggle shortcut by default (F9 and F10).

* Clean up.
