Updated submodules and basic configuration for Golang
Updated all submodules with `git submodule foreach git pull` and added to .vimrc
basic configuration for using Go inside VIM. Need to figure out why I have to
symlink the default Go directory inside bundle.(vim-pathogen doesn't let me add
the path to the rtp).
