Rebuild wufoo form / chuck embedded version

**No need to merge this yet**; I wanted to write down the things that still need to be done. Feel free to post feedback. I do know that some of the webserver stuff is ugly- it needs refactoring at this point as I just got it working.

- [x] Create error page for when wufoo POST fails
- [x] Pull wufoo junk into local lib module
- [ ] Tests?!?!?!

Functionally, the wufoo form rebuild is just about there. There are a few more things once its done but I'll track those elsewhere.
