Recognize trailing [tag] on folder, guard metadata tags

Folders that carry their release tag as a bracket at the end
(rather than a -TAG suffix or [TAG] prefix), e.g.:
  Gravity Falls 2012  Season 2 Complete + EXTRAS 720p BluRay x264 [i_c]
now have that tag ([i_c]) prepended to the episode filename.

Also fixes a real bug where a title's own hyphenated word (e.g.
"Scary-oke") could be mistaken for a "-GroupName" suffix; the word
before the dash must now itself look like quality/source/codec
metadata for that pattern to fire.

Every tag-extraction path (file dash-suffix, file trailing-parens
group, folder dash-suffix, folder bracket-suffix, folder bracket-
prefix) now also refuses to promote something that's obviously a
metadata token itself (e.g. WEB, 1080p, HDR, WEBRip) to a release
tag.
