[aur-dev] Method to get all packages

Hey all! Loui Chang pointed me here since I prepared a patch to get all packages from AUR via the rpc-Interface... The reason why I need to get all packages is to build a list of available packages (which gets cached then...), the user can search in it then... (or just dig a bit in it...). This all is for the AUR-Intergration into Shaman2 (you might probably already know the 1.x version which is in community...)... Now the patch is attached, it's not tested at all and I don't have much knowledge of php/sql/json at all, so it's mostly a copy-over from the other methods... Lukas
