Implemented basic cursor drawing for hair edit mode brushes.

Fix for brush radius, the Brush.size property is actually the radius and
not the diameter.

Support for common operators, keymap entries and radial controls for
hair brush settings.

Apply the same weight profile in the comb tool as in particle edit mode.

The comb tool will likely get a complete overhaul, but until then it
should just behave like the old tool.

Fix for OpenlGL state restoration after strand drawing, disable color
material option.

Added back different selection modes (strands, verts, tips) for hair
editing.

Show selection state of hair vertices with the usual theme colors.

First selection operator implementation for hair edit: circle select.

New mesh sample evaluation function for shape key data.

Generic raycast method for generating mesh surface samples.

Conflicts:
source/blender/blenkernel/intern/mesh_sample.c

New simple storage method for single sample values.

Better feedback about valid sample from mesh sampling methods.

Conflicts:
source/blender/editors/object/object_shapekey.c

Fix for uninitialized return value.

Basic Add tool for creating new strands in hair edit mode.

Define hair edit settings and brush types in the RNA, similar to paint
and sculpt settings.

Lots of small fixes for paint system quirks to make hair brushes work
in the UI.

Simplified first version of the hair stroke combing functionality.

Stroke tools will be categorized by the hair elements they operate on:
vertices, segments or strands (roots). In addition to that a filter
function defines the influence of the brush. This should be defined by
the other brush settings and be largely independent of the main tool
mode.

Nicer vector math for mouse coordinates.

Apply the hair matrices when converting from particle keys to bmesh,
so the edit data is consistently in object space.

Missing bmesh include folder for hair editor in scons.
