This adds suport for user to add per package post install actions, somewhat similar to post-install scripts in packages but controlled by local user and not part of package/not done by package maintainer. The actions is performed by "system" call and can't contain spaces (not even when inside "). Syntax in logfile is PostInstallAction = <packagename>:<action> Functionality added inside libalpm, add support for configuring in pacman.
