Refactored all submit reqests into a new package.
Got tests working again. Turns out redirecting standard out was breaking lettuce because lettuce uses standard out. I improved _execute to give slightly meaningful names and turned on verbose for all tests that need it.
Merged refactor_Submit_Feature with master. Fixed some merge conflicts. Installs and tests run fine now.
Merge pull request #78 from dblodgett-usgs/refactor_Submit_Feature

We can discuss and modify later, not going to get any more broken than it is.
