Vim integration

[cjrh]

I would like to make a vim bundle for driving easycython. Firstly, the cython support for vim must be improved to highlight correctly (it seems like cpdef for instance is not recognized). Then, the plugin should allow launching easycython on a file, and (configurable) automatically open the annotation html file in the system browser for inspection. It would be awesome if compilation errors could be traversed in the .pyx source.

Hmmm, I think the syntax highlighting issue is fixed by https://github.com/tshirtman/vim-cython
