[yt-dev] 2.6.2 on Thursday

Hi all, We've had a couple critical bug fixes go in to the mainline 2.x branch lately, and we're also slightly overdue for a 2.6.2. So I would like to cut a release on Thursday. If there are any objections, let me know, otherwise I'll proceed with merging into stable, tagging, and uploading to pypi. John ZuHone pointed out that with Kacper's fixes to the packaging and his fixes to various imports and whatnot we ought to keep to this schedule; I've let it slip a little. -Matt
