[Bf-python] RVKs

[antont at kyperjokki.fi]

just a short note, (to get this out of my mind)

was looking a bit into how to work with RVKs from Python, and found out about 
the existing NMesh.insertKey, with the note 'Warning: This and removeAllKeys 
were included in this release only to make accessing vertex keys possible, 
but may not be a proper solution and may be substituted by something better 
later.'

.. with <stivs> we figured that that time might be now, but after a little 
talk with Ton it became clear that it's better to wait a while. he's still 
pondering what to do with all the different animation things there are .. 
rewriting NLA being the next in todo i think, and he might put RVKs to 
Actions or something .. we'll see. in that case it would not really make 
sense to have NLA in the Armature module (did it ever?), and i guess the 
whole NLA will deserve consideration (a new top-level module?)

getting RVK/slider access to Python is not urgent for Orange, so that can well 
wait. just got a enthusiastic about it for other reasons ;)

dunno how relevant those things will be for you, nor what exactly we will 
need, but time will tell .. and there still is some :)
