New plugins: color tools

[tkbd]

I got a weird segmentation fault11 crash just after Wings3D quit in MacOS.
I haven't tested on Windows, does it happen on Windows too?
I installed last patches to Wings3D, so it caused by the plugin.

How to recreate it

1. Run Wings3D and open/close a Color panel window (Window > Color Panel window open)
   
2. Create a Cube object in 3D geomerty window.(or do some operation for Wings3d)
   
3. Quit Wings3D
   
4. MacOS crash log window appear by segmentation fault.
   

his phenomenon seems to have stopped once Wings3D is closed with the ColorPanel window open.
But when do something and quit Wings3D, it reoccurs.
