Changed git.plugin.zsh > added an in_git function

Added a netpunk.zsh-theme … displays battery charge remaining using batcharge.py, date, ruby version via rbenv, points out werther you're in a GIT or HG repository, has improved HG functions, but requires hg plugins prompt, tasks and mq. I built it, and now it's up for grabs :)
