3.0 API update
Add ability to import collections, add (back) role photos.
fix indentation
Removed some TODO's (determined opensubtitles hashes are not supported for sure, also determined that API *does* fall back to "en" if nothing is found for specified language, despite documentation saying otherwise).  Minor tweaks to collection adding.
fix indents again (back to spaces…  sorry about that…)
