Get weights inputted into leveldb

i'm pretty sure that this isn't the way i want to layout the db. i'm not
sure using a key for all users and then separating out their weight data
under a key of their name is a good idea. i'll roll with this for now
though.
Just keep everything in leveldb in the users key
Fix debug message
Update db location
