Merge pull request #27 from jeremyfelt/develop

Merging v0.3 from develop branch
Added .vimrc file to customize vim.  Also changed provision.sh to link to the vimrc file just like we already do for .bashrc file. The items in the .vimrc file currently make the save file command :wq case insensitive and also will do sudo automatically when saving a file as non-root where sudo is needed
