[ANN] Open source MobGUI iOS controls - first draft

[John Craig]

A while ago I started rewriting some controls to use the new before and 
after behavior handlers.  The results are custom controls with no 
library code in their scripts - I think it's a lot cleaner.
The link below is to the first draft.  The library is a one button 
palette.  Just use the button to attach a copy of the library to your 
stack.  After that you can close the original palette as it's not needed 
any more.  The palette now attached to the stack is the one that you use 
to drag custom controls from.  Any time you open your stack in the 
future, you still just use the attached palette.

I've added a few iOS controls to this palette - if feedback is good and 
everything works as expected, the other controls can be added.
My tests showed the controls to scale for normal/retina with no 
problems.  Thanks to Dixie who also gave it a test on 5.5.3 and community.

There is a slight glitch on the NavBar - after initially dragged on to 
your stack, you can double click to snap it to the top of the stack, but 
it's height is slightly too small - dragging a resize handle solves the 
problem for now.  Each control has an 'mg' custom property set.
