from Sebastian Nell (codemanx)

Various fixes to UI messages (among other things, all messages needed it should now be capitalized).

indentation edits and copy pyrimid from contrib (where I had made some edits), removed so this wont happen again.

Beware: in mocap/__init__.py there was a very long bl_label (> 100 chars), which was troncated in UI (at least, _update_msg.py produced a troncated msgid for it). That should be avoided, imho!

* You only have to do layout.prop if you want 1 property, no need for row then!
* Use col, row, sub as variable names, not colsub, rowsub, row2 etc please.
* Povray Addon: Still used a lot of splits, you need no split when you only have 1 column! 

thanks to Benjy Cook
well done!
