Commits for Relation Select

Fix code formatting from last commit.

This is about as good as it gets for now.  All things should work as before, with interface a little different.  File uploads still don't work.

Remove _relation_select_field_widget_multiple_form.

OK, this doesn't work, but I learned some shit about how this all goes together -- apparently the field system doesn't loop through for each field instance, so we do our own little jig??  WTF?  Committing, so I can go back to square 1 on 7.x-1.x.
