Added zprezto as a submodule repo
Renamed dot to bootstrap
Shamelessly copied Zach Holman's bootstrap script

Applause for @holman and https://github.com/holman/dotfiles
Modified bootstrap to be used by Zsh
Appended .symlink to all dot files.
And removed bash files, because I don't use bash anymore.
Updated Vim plugins
Added .gitignore
Improved Zsh setup in bootstrap

setup_zsh is using the same link_file function to link the runcoms
in prezto.
Add check for the default shell.

Only attempt to change the default shell, if it is not already Zsh
Updated vpm script with the new vim file names.

i.e. vim/ -> vim.symlink/
