With changes in DF the GUI Window looks different, and the buttons look out-of-place.

To do:

1. Add an option to hide the buttons and instead access the functionallity they currently provide via right-click anywhere on the window.
   EDIT: This is hard to do with AceGUI, because the "Dropdown" widget is by default not expanded, and there is no public API to open it. It's likely to be messy fixing it like this.
2. Make sure defaults are not changed.

1. Fix #11. There, add the functionallity of the buttons.
2. Add option (default=false) to hide Window buttons.
