Consolidated several separate implementations of the same weighting algorithm into common_sql_weight() and fixed some bugs...
For MySQL, now using timestampdiff() instead of subtraction for the comparison, so we get sane results when the year doesn't match, and utc_timestamp() rather than now() so we don't get negative ages for recent items with local server timezone.
Unknown whether the same problems affect PostgreSQL, but note that it lacks the timestampdiff() SQL function.
There's great value in knowing that something doesn't exist. We
now cache this information, and carefully compare the results from
cache as $results !== false instead of !empty($results), since some
empty values (null, 0, empty array, empty string) are stored in the
cache.
Caching staticGet() and pkeyGet() now store DB misses in the cache,
and cachedQuery() checks for empty results from the cache.

There were some problems with the automated cache/uncache system
for data objects that made us cache unfindable keys (with null
attributes and sometimes null names). Fixed those problems and
refactored the encache() and decache() methods so they use a helper
to find the cache keys to use.
Allows storage of larger objects (over 1mb in size uncompressed), such as huge LDAP schemas.
Should also improve cache efficiency (allows more stuff to be stored in same memory) and reduce network latency (less data transfer)
(redo commit 1e9c03e199 which was apparently lost during pluginization)
I modified the SamplePlugin to show how to do some real processing,
adding a data class and an action class and modifying the main
menu to link to the new action. I added documentation comments to
all the methods and made sure the modules were PHPCS-clean.
