dwmloop had a '&' inserted (how the hell...)

* Caused dwm to constantly restarting itself; wasn't really fun.
* Added alias for sane use of info.
* Added alias for handy use of ayemake.
  => ayemake now also forwards arguments (such as 'all', 'clean', etc.)
* .xinitrc hashbang has been re-changed to /bin/sh
  => backwards compatibility for the non-/usr folks
