Improvements to smilart's agnoster theme fork:
- Replaced special characters in the code (fixed bugged characters, currently works with powerline fonts)
- Prompt is shorter, shows only the last directory
- LS Colors match iTerm's Dark Solarized theme

to do:
- Fix tab completion: tab completion should automatically work on special characters (such as '[')
right now you have to escape such characters for tab to complete it `\[`
- Set it up to work over SSH
