fix: add Races, Clans and Companion Actions to auto-translate

The Race, Tribe and BuddyAction sheets were skipped as the default
behavior was to include rows from `0..^0` if no range was specified in
the Completion sheet. That range would usually include everything, but
since the ranges were iterated over as integers there is no "last" index
so `^0` equals zero.

Also preloads the AutoTranslate cache on plugin load in a new thread to
avoid a hitch when sending the first message. This behavior is disabled
in DEBUG builds to make profiling easier.
