ignores my user settings in /etc/passwd, and tmux support

[sanguis]

First off this looks awesome. tons of promise. I am not complaining bellow just informing you what I encountered on my first run

I use zsh, and tmux in all sessions.

When I start the app it starts with a bash prompt. When I run "tmux a" to attach the session, tmux is not able to redraw the screen properly and is constantly scrolling around oddly.

I can not see the tmux bar ect. The borders are not being drawn right. Moving between buffers is extremely slow.

Thank you for your feedback! zsh support is being tracked in #26; the tmux issue is a subset of #121.
