- local tentative fix for BLI_gethome(), which returns '.blender' appended only
    on some Windows systems.  Created bpymenu_gethome() to check and
    add '.blender' if needed.
- changed name: .Bpymenus to Bpymenus as suggested by GSR
- trivial additions:
    Object module: added methods .set/getSize
    Armature/Bone module: bone.set???() methods now accept both n
    floats or a list of n floats: fff or (fff).  All these additions were requested
    by user Carlos Lopez (Klopes).
- New doc: for module Registry.
