Removed title index field from search indexes.

The title is already being indexed in the text
document.
Updated copyright date.
Updated my email address.
BACKWARD-INCOMPATIBLE: Moved from custom save method to auto_now(_add).

This may be an arbitrary change, but I want less code that to be
accountable for. Using the auto_now attributes means fewer tests
to write.

The main difference is that now Topic and Question `modified`
fields will never be `NULL`. Rather, they will always have a date.
Previously, an item that was created but never modified did not
have a modified date.
Re-ordered/organized/prioritized the TODO list.
Accept and pass args and kwargs in custom save method.

While writing tests, creating a Question object
threw `TypeError: save() got an unexpected
keyword argument 'force_insert'`. Checking the
Django documentation I learned that args and
kwargs need to be accepted by the custom method
and passed to the default one.
BACKWARD-INCOMPATIBLE: Removed template_name field from Topic model.

This is a feature that made little sense given the various
URL/view setups. Using the topic slug as a class or id in the
template should give enough leverage for visual customization.
Reorganized, but did not finalize, pip requirements files.
Removed old, unused tests directory.

New tests will soon show up within the faq
directory. I put these files here before I
understood what I was doing with tests.
Added ability to use custom search index class.
Removed save_as=True from question admin.

It was silly. Save and add another makes more sense.
Added initial tests.

I still need more, but this is a good start.
Added .rst suffix to README file.

Also rewrote and reorganized the contents.
General commenting, removing unused imports.
Add initial framework for docs.
Add VERSION to package.
Change package URL.

Go HTTPS!
Add basic INSTALL instructions.
Alphabetize .gitignore entries, remove egg-info.

I don’t distribute eggs anymore.
Define source code encoding.

Why? Because.
