IDEA: Flag material slots as "clothing"

[arionsh2]

It would be nice to split mesh materials into two categories:

• "body" materials, which always change on transformation
• "clothing" materials, which might not change on transformation

If "clothing" is designated on an avatar, a radiant menu should be setup on the avatar with the following buttons:

• 1 toggle button for each clothing piece (On/Off)
• A toggle button to make ALL clothing static, or make ALL clothing change with TF

If a clothing piece is off, it should never display regardless of statue state.
If a clothing piece is on and clothing is static, the normal texture should use a static version of the untransformed texture (no slicer or alpha driving). The statue version should always be disabled.
If a clothing piece is on and clothing can change, the current configuration of materials / slicers should be used.
