GitLab

If the svn plugin is used, svn info (repo name and wether the repo is dirty) is displayed in the prompt like with git. Just lke with git, the colors can be manipulated with variables (see awesomepanda theme for example).

Theme based on clean that is more suitable for white background
terminals.

- simple theme
- hostname and current folder on left prompt
- git branch and working tree status on the right

adding my zsh theme -- only difference from robby's being that i'm using white instead of blue for legibility over brown

instead of just git
