[Bf-python] set*(3float) bug & obj.setSize() request

[Carlos López]

Hi all. Such as happened with setLocation and so, for bones at Armature module:
*.setHead(), .setTail(), .setLoc(), setSize() and setQuat() don't work, and send:

Attribute error: expected 3(or 4) arguments

*At the other side... there's not both get/setSize() functions in Objects module...! Must I access to it through SizeX/Y/Z instead?

See yah
