[WIP] New ebi submit [WIP]

Almost there, but I thought I'd get this in now so that people can begin reviewing, it's kind of big.

Needs:
- [ ] Logging
- [ ] Test code
- [ ] Script file (this is the library code)
- [ ] Final step that calls ASCP on the XML files generated
possible to have 'qiime_study_' set as a static or member variable? Ie, something that could be changed on subclassing or on construction?
