Add automatic plugin activation for vim
Add several vim plugins

Added are:
* ctrlp
* vim-a
* colorsamplerpack
* yankring
Remove wrapVim

I don't see a reason for having wrapVim function and vimWrapper and
vimHugeXWrapper packages. If you need a system vimrc, whats wrong with
``environment.etc."vimrc".text`` ?

Also strictly speaking ``vimHugeXWrapper`` didn't wrap, X-version
properly. I.e. running ``gvim`` have console vim version.
