instead of recursive bytes2unicode use a proper JSONEncoder to conver bytes->unicode for json.dumps()
removing excessive isinstance(data, bytes) checks
py3: / -> // and list() around .items() that gets modified in loop
moved lbrynet.undecorated to where its actually used and hopefully we can delete it eventually
removed build/upload_assets.py, travis can do all this now
-remove stream info manager (DBEncryptedMetadataManager)
-split `add_lbry_file` into separate `add_published_file` and `add_downloaded_file` functions
-set the download path upon adding file to the db, use the source file path for publishes
-remove the lbry file manager-wide download directory, set for each file individually
-add claim `metadata`, `claim_name`, `claim_id`, `outpoint`, `txid`, `nout`, `channel_claim_id`, and `channel_name` attributes to EncryptedFileDownloader
In the next commit I change conf.settings to be initialized
at runtime instead of load time and so any import of
`from lbrynet.conf import settings` will be and stay None if
it happens before the initialization.
