New OB_GROOM type for hair editing objects.

Use material slot index instead of a direct Material pointer.

A Material pointer would be a nicer way to assign a hair material,
but unfortunately that does not work well with the context-based material
lookup of the node editor. There is no selection of an "active" modifier,
so the node editor will never display the material (unless it is placed
into a material stack as well).

Material pointer in hair systems.

Simplified API for generating hair follicles with a fixed max count.

The final count is inversely proportional to the min_distance, so using that
as a user variable is difficult to control. Instead we just use the overall
count as the single variable now.

The actual final count will be less than this maximum count, because the
theoretical limit is never reached in practice. The min. distance could also
be stored as a result of the hair generation as feedback for the user.
