Handle remote sessions that have changed user

Previously, if you were connected via SSH but had changed user with
su/sudo, the _lp_connection function would report you as being connected
via telnet. Now, if the parent process of your shell is 'su' or 'sudo',
it sets the hostname to the color LP_COLOR_SU (default: bold yellow).

This is probably only useful for people who have installed liquidprompt
in a global location and run it with a globally-accessible shell config
(/etc/profile or similar). But since there's already code to handle a
current user of 'root', I assume this has already happened.
Add Archlinux PKGBUILD.
tmux support. Cleanup of _lp_jobcount_color. Adds number of screens sessions and number of tmux sessions as a total of detached sessions.
Only match detached tmux sessions, not all.

bad regex warning in zsh (#127) and it didn't worked in submodule.
Plus, bash and zsh regexes have perlish syntax.
