Changed symbol for scratchpad.

* Alright, basically removed the symbol.
* Adapted dzenconky size, as a concequence.
Refined urxvt.

* Refined urxvt configuration in .Xresources.
  => added perl script for opening new window in same PWD.
* Fixed hinky vimrc lines to be more correct (and thus work well with urxvt).
* Added '.' as a word-seperating character in vim.
Back to bash!

* There is either:
  a) zsh not playing well with VTE based terminals (xfce4-terminal, for example)
     and thus driving me nuts (see this entry:
     https://bbs.archlinux.org/viewtopic.php?id=159822
  b) zsh playing well within a non-VTE terminal, of which all of them are either
     laggy as hell (urxvt), not configurable, and/or not supporting UTF-8 (xterm
     and a shitload of other terminals).
  So I decided to ditch the advantages I got from zsh in favour of a reasonably
  working environment.

* Fixed patched 6x13 font for getting it to work within urxvt.
  => still doesn't work within urxvt, but hey, I fixed it!
