Updated patched font for vim.

* Renamed to 'AyeFixed'; only necessary glyphs are contained now.
* Added fonts.dir file.
Added back urxvt.

* Still rendering as hell, but it's getting acceptable.
* Added shortcut for opening urxvt (of course with zsh ^^).
* Added necessary entries in .xinitrc for starting the urxvt daemon and adding
  the patched font path.
