[aur-dev] Turkish files and more.

Here are a bunch of patches to clean up some obsolete scripts and files in the AUR codebase. The only change to the working AUR is that Turkish language files are included and enabled. I'll push this in a couple of days if there are no objections. 73f807a... Remove obsolete Trusted User guidelines. b69e2cc... Move top page template-example to web/template. 361f08a... Remove obsolete sample PKGBUILD and tarball. bbebc08... Remove obsolete test scripts. 1d416d6... Add Turkish to SUPPORTED_LANGS in config.inc.proto. af1394f... Add initial Turkish language files. They're too big to send to the ML at once so you can find them at http://louipc.yi.org/aur-patches
