[PATCH v2 2/2] contrib: vim: add sharness syntax file

[Felipe Contreras <felipe.contreras@gmail.com>]

It gets a bit tedious to see all the tests in the same color, so I
wrote a vim syntax file to relax my eyes.

I've tried to make it work in as many situations as possible, yet there
are still some issues with HEREDOC strings.

Much better than nothing though.

This can be enabled with the following pattern:

  au BufRead,BufNewFile */t/*.sh set filetype=sh.sharness

Whoever, that's already added to the project .vimrc.
