Fix psql prompt color/corrupted history bug.

psqlrc
	-`psql`'s history would become corrupted as I scrolled through
	it, appending snippets of text to my command-line. Fixed by
	removing the wrapper `0x01` (`%001`) and `0x02` (`%002`) from
	both color codes (http://stackoverflow.com/questions/19139330/colors-in-the-psql-prompt).
Add Xresources, remove gnome_terminal/.

Xresources, gnome_terminal/
	-Add my current `~/.Xresources` file, with some config
	statements for the `xterm` terminal.
	-Remove old `gnome-terminal` config.
	-`xterm` is now my terminal of choice.
