Simplified Catalyst

[M-C-McGrath]

We should change our current Catalyst form to be an "advanced" form (much like the advanced search forms that are prevalent) so that we can keep much of the functionality, but default to a simpler form instead. This form should have the following defaults-

Search Settings: Don't allow filtering the documents at all. Just run over documents and emails (not entities). Run over all documents.

Choosing Catalyst Methods: This can be similar to the advanced settings.

Settings: The same defaults as in #75 should be used, but the user should not be able to modify them. That means that in many cases the user will only need to choose what input method they want to use (if there are no settings to choose, such as entity extraction) and nothing else at all on the whole form. In others, where the Catalyst method requires user input (such as term lists), the user will need to be prompted to enter these settings.

The current form should still be available so that the full range of configuration is there, just not as an obvious thing. We can write a tutorial on the configuration options on the advanced form once we aren't changing the UI too much anymore. The simple form should be usable by nontechnical users without instructions, ideally (or with minimal instructions when entering settings on some Catalyst methods).
