[WIP] Works on sync and removing get_content call to download comment data. NOT TESTED! Probably will mess your db badly!

[JES] Update schema to add a new index. Also changes an index that we decided we'd rather have the full verson of. Re-write get_disccuion_by in condenser_api to look nicer

[JES] Update to the mutes checks. Don't clear the cache every hour, instead simply remove a user from it if it's detected that they have been removed from the blacklists

[JES] Fix bug in pagination on get_account_posts. SQL query was being incorrectly built when start_author and start_permlink were specified

[JES] Fix bug when there were no posts found. (not a crashing bug but was causing some exceptions to get thrown)

[JES] Update schema to update the creation of an index (currently partial but we decided we'd prefer to have the full index since many posts are not 'deleted'); add comments to sql queries to aid in tracking down slow ones from interfaces like pghero (queries get truncated and it's not obvious which one pghero is referring to, but a comment at the beginning of the query will always be displayed so there's no guessing)

[JES] Redo the get_discussion method. Still needs some work but should be a good improvement over the old one for now. Also clean up some debug logs that got left behind

[JES] Fix a bug in handling follow operations. The 'what' was indeed a list, and the first element is expected to be a string but was a dict instead of a string, leading to the dreaded 'TypeError: unhashable type: dict' problem.

[JES] Fix pinned posts. Code needs a little cleanup still but trying to get things back to a working order first

[JES] Fix get_ranked_posts viewing 'my' communities. I was joining on author instead of observer which was giving incorrect results
