Code review comment for lp:~georg-zotti/stellarium/gz-better-anglemeasure

I found how to make functional groups in the GUI now. The checkboxes in the group boxes are 1-2 pixels smaller than the single checkboxes, don't know how to fix that.

On the author list: All "contributors" (listed only in the plugin's own config panel) are now in the author list (visible in list in main program's plugin config dialog).
