Autostart: run thunar once
bash-utils: add bu-fun-run-if-exists
Add gtk key theme
use xresources colors for dmenu

* bash-utils:
 - add 'bu-sys-xresource' to bu-sys
 - bu-log: pass the pid in the message tag to the logger.
   (-i option is not what I was looking for)

* dmenu.sh:
 - use 'bu-sys-xresource' to get dmenu colors
 - log with bu-log
