[pacman-dev] new script: repo-local-cleaner

[Alessio 'mOLOk' Bolognino]

Hi list, 
this is a script I wrote for myself, but Roman suggested me to send it
here, so... here it is: it's a script that removes old packages in the
local repo and optionally runs gensync at the end.
I tried to follow the standards of makepkg, feel free to ignore it,
change it, change its name and things like that.
You can even change the copyright line and put Judd's name if you want.
