[sldev] [Patch] VWR-6918 Tools menu option to hide selection outlines

[Aimee Trescothick]

I have just attached a patch to VWR-6918 adding an option to the tools  
menu which make it possible to hide the selection highlights while  
building. This is of great use while using very small prims, or  
aligning textures.

The current work around (http://wiki.secondlife.com/wiki/Video_Tutorial/Turning_off_object_selection_glow 
) is extremely inconvenient involving changing the  
SelectionHighlightThickness debug setting and relogging every time you  
want to turn them on or off. Having a menu item to turn them on or off  
means that they can be toggled on the fly without even losing your  
current selection.

I'd appreciate any feedback people may have, and if someone could  
review the patch with a view to committing it to http-texture.

Aimee.
