First import of various dotfiles
Added support for Go
A major refactoring that replaces the forked spf13-vim in favor of the
latest version of spf13-vim. The latest version is flexible enough to
support bundles without git submodules, which makes the fork
unnecessary.

In addition to the vim refactoring I have introduce bootstrap.sh to help
setup a new environment. It currently just handles the basics: linking
dot files, installing spf13-vim, and installing oh-my-zsh.
