This explicity sets the caching behavior for all goodies. Goodies which
did not have caching behavior set in their package have had it added.
Similarly for the tests.
This resulted in a number of changes for caching behavior, mostly
moving towards more frequent caching.
I identified three cases where goodies should not be cached. They are when
the result depends upon:
- some random element,
- the time of day or year (as with relative dates), or
- the location of the requesting user
In all other cases, I presumed that the goodies were sufficiently
deterministic in their output to warrant caching.
Reducing scroll spam from dzil by:
- Providing ABSTRACTs for all packages.
- Leaving VERSION vertical space where necessary.
Addresses #600 plus other annoyances in the process.
I also limited the triggering to exact matches because it's really hard to distinguish between non-suicide queries ('suicide girls', 'suicide silence', 'suicide is painless', etc.) and suicide queries. The plan is to just build on the list of suicide-y queries as we go along.
