Added colors for gnome-terminal Solarized theme.

The solarized theme doesn't work properly in vim without setting the
theme for the terminal. Additionally, dircolors are added to get
proper colors for filetypes in the terminal.
Added a list of sources for the things present in this repo.

Hopefully this will make updating external sources easier in the future. I'd like
to automate the process of doing updates in the near future via some
shell script or other mechanism.
