Merge remote-tracking branch 'origin/Ar'
1. Changed the buttons that has too much opaque backgrounds. Playing
with the resizing of buttons with different dpi. The resized buttons are
not yet included but I think it is not the problem. The problem is the
wrapping or something of the image button. 
2. The Database is actually working right, I just thought it doesn't
save but it actually does after a closer look.
Added all the images for different DPIs. The UI for the selection of the
Server and client and such isn't finished yet.
