[aur-dev] [PATCH] Use PEAR modules when submitting PKGBUILDs

pkgsubmit.php now uses the PEAR modules Archive_Tar and File_Find for finding the PKGBUILD and messing with tarballs, Archive_Tar should be installed by default but you'll need to install File_Find yourself to make this work. I've also done some other cleanup such as (aside from rm_rf) no more exec use and changing some variables around. As far as I can tell this setup is actually faster than what we have now and I know it's much cleaner (compared to before, that file is still a mess) and it's also much more reliable for finding files. Fixes FS#2900. -- Callan Barrett
