Core: Add wintergrasp-patch to wintergrasp_cleanup branch - resurrected from an old work-repository, now over as a branch to work on.

Original patch by socolin, cand a ton of contributors :
mathman, joda, spp, silinoron, josh, malcrom, shauren, machiavelli, click, rat, leak, tobmaps, _manuel_, the tcfr team (via socolin), and tons of others for chiming in.

NOTE: THIS IS A WORKING-BRANCH, AND _NOT_ MENT FOR PUBLIC USE OR EVEN CONSIDERED STABLE!
