HEY EVERYONE, I'VE MERGED MOST OF THESE PRS INTO fprimex:eventbrite-plus-prs

I've made an attempt to consolidate most of the changes made via PRs in a branch. Have a look:

https://github.com/fprimex/zendesk/tree/eventbrite-plus-prs

You can pip install straight from here for testing and installs:

https://github.com/fprimex/zendesk/archive/eventbrite-plus-prs.zip

The only PR I think I did not get was this changeset, as it seemed a little too heavy handed and worth a 2nd look to me:

https://github.com/akihiromatsumoto/zendesk/commit/004e4874391856ffbc1f52d39b2d5a209c18969c

I'll be continuing work from this branch, fixing problems, and trying to keep it up to date with any more PRs that get made against eventbrite:master.
