Transplant the editor and associate editor forms into place from the formcontext.  This involves quite a few subsidiary changes:

* separate out tests for specific formcontext implementations, and provide a success test case for both the editor application review and the publisher reapplication
* fix a bug in the xwalk around handling suggester information
* minor update to Suggestion model object related to above bugfix
* remove the outdates suggestion.py and associated editor suggestion jinja template
* separate out the "lock" feature into an includable jibja template
* tidy up the imports in doajservices.py, which depended on but didn't use use old suggestion handler
