- Sources now have machine annotation on (instead of off) by default.
- The Edit Source page now correctly shows the enabled status of the machine annotator (fixed a really stupid bug).
Fixed display of the new source form; it had an extra 'machine annotation' header.
Annotation tool: (1) New annotation tool setting: "Show machine annotations". (2) Added a system for displaying field help text in a separate dialog (this was originally from an in-progress upload branch).
Annotation tool: the option to hide/show machine annotations now actually works.
Added the DB migration file that adds the "show machine annotations" setting for the annotation tool.
No more machine annotation disabling upon request; only enabling.
