Clean up the patch-y cheese

First up: common-inc-autocomplete.

People understandably get a little freaked when asked to patch core modules, and especially when patching something as vital to Drupal working as common.inc. ;P

This patch (along with bits of the taxonomy and user patches) adds in 4.7's AJAX functionality to 4.6. The only module that makes use of this is gjg_event module, which uses autocomplete in order to provide a selection of venues for the event.

There is also an AJAX module, available from http://cvs.drupal.org/viewcvs/drupal/contributions/sandbox/thox/ajax/ - however; I did not have luck getting this to work with the drop-downs when I tried this a couple months ago.

There is also the matter of most testers who have tried to add events and venues finding the interface very clunky to use. It seems like autocomplete is not the right interface to use here at all, though I'm not sure what is (a massive drop-down with 50,000 venues doesn't exactly seem like a step up...). I should note though that I think AJAX could definitely be a boon to allowing venue creation without leaving the event creation form, but this could be slated as a 4.7 feature, rather than having to try and smoosh it into 4.6.

Verdict: I will try to replicate this functionality with AJAX.module, and failing that will strip out AJAX altogether and just revert to a drop-down for venue selection. This patch will be REMOVED.

sorry, going to have to postpone this for now.
