Added a Reduced Quality checker

This checker runs the following tests:
untranslated, unchanged, blank, doublespacing, doublewords, and spellcheck.

It's meant for cases where source strings aren't supposed to be similar to target strings
(e.g. when source strings are slugs), so it intentionally omits any checks that make
assumptions about matching source and target syntax.

It's larger than the Minimal checker though, by including three more tests that shouldn't
usually trigger false positives under such circumstances.
