Derivative map baker

Added support for derivative map baking, which
is accessable as a dedicated baker type. Works
pretty much the same as displacement map baker,
but gives you derivative map.

In fact, inernally this baker is just a filter
which applies on the result of displacement map.

Both regular and multires baking are supported.

Patch by Morten Mikkelsen and self.
