Gtk3: fix failing item-edit widget on sheets

Browse Source 
There were several problems since the conversion to gtk3
* widget wasn't displayed at all - apparently this was because I had overriden the draw function of the gtklayout (sheet)
  -> fixed by adding a draw callback instead
* several gtk warnings about allocating sizes to widgets without using *get_preferred_width/height
  -> fixed by adding the itemedit dropdowns to the layout only when they are requested
* the arrow button didn't want to resize small enough
  -> fixed by adding a custom style to drops the button's internal padding
* there were several sizing issues which ironically got fixed dropping much of the custom sizing code
