[Bf-committers] I would like to add a "rearrange Material slots" feature

[Gaia]

Hi;

I propose to add "Rearrange of Material Slots" similar to what we have 
for Vertex Groups and Shape Keys.
Rearranging of the slots should keep all material assignments of the 
active object intact of course.

@Campbell:
Please could you post your opinion about this?
Does it make sense?
Would this have to be added in C or in Python?

thanks
