sfepy over web

Hi guys,

I think we should get sfepy running over web. I have setup a Sage notebook and it seems that as long as we can safe something to a png file, we can work with this over a notebook.

Also, we should try to merge it with hermes, so that we can just develop one (good!) FEM library and benefit from each other.

Looks like some exciting times are ahead of us. :)
