Started on db consolidation.
Continue db utils cleanup
Cleanup with no errors
Got deadlock fixed
switch db connection back to an instance variable.
Continued work on db_utils
added index to db_info table; fixed unpack from get_all_favorites
give get_favorites a better name
centralize sql code to minimze deadlock and maximize reuse, rename
get_subscriptions since it doesn't always get all
Moved __execute with the other internal functions
More db_utils cleanup
Moved metapack code to metapacks.py; moved repair images code to
db_utils
Switched unsued variables to be assigned to _ to avoid code warning.
