This commit gives the solidify modifier the ability to assign the newly created shell and rim geometries to selected vertex groups. This expands the procedural control over the modifier stack by letting users apply modifiers to the shell geometry without affecting the original geometry. This will be especially helpful for NPR users that use solidify to create backface culling lines on their characters giving them the ability to add displace noise and other effects.
