Modifiers: Armature deformation test for various modifier settings

Browse Source 
Test for armature deform modifier settings that are not yet covered by other tests:

- Vertex Group vs. Envelope deformation and both combined.
- Vertex group masking ('vertex_group' setting of the modifier)
- Inverted vertex group masking
- Preserve Volume (dual quaternions)
- Vertex Group/Envelope influence mixing (bone option)
- B-Bone deformation
- Multi-modifier mixing

Each case has a new test/expected mesh pair in the modifiers test.
