autodetect indentation

[anatoly techtonik]

Vim already comes with a good syntax highlighting default, but editing files with 2 space indentation is a disaster. All indentation aware editors correctly detect this setup and are able to indent and dedent lines correctly, but not vim.

There are a couple of plugins that fix the issue, even though I think that it is a usability bug in vim.
