fix board_id entry name
update epochImporter to use boards, threads, and posts from core

these are currently broken due to high amount of connections.
update config to work with new lolipop config format
update board/thread/post streams to work on a shared lolipop
update epochImporter to work with new board/thread/post implementations

they now take in a lolipop as input (so that they can share it)
handle err in callbacks

needed to use the data on callback to get the new id since the data
returned isn't just the new id data; it is the entire new object!

when the code wasn't handling errors, the new object was actually null
instead of what it should have been
old id's are now derived from the new object

when deriving them from the original variable in the call above, async
causes the values to be undeterminable.  instead, use the object in the
callback to reliably set the old smf id of the parent object.
