-fix daemon functions to start/stop lbry files
-remove unused stuff in LBRYFileManager
-improve and use new get_lbry_file function instead of _check_history,
which didn’t use the lbry file manager
-use said function to let delete_lbry_file use the same search keys
(sd_hash, name, and file_name)
-logging in LBRYDownloader
-Add LBRYFileProducer, to host the contents of a download without
having to keep re-opening it as it is added to
-included sd hash in ManagedLBRYFileDownloader, to make comparing the
contents of the file manager against name claims easier
-add get_lbry_file function, which returns information about a LBRY
file found by sd_hash, file name, or lbry uri
-make is_lagging more meaningful - it is set to true after 90 seconds
with no progress, this is to stop slow but steady catchups from
triggering it
-prevent situation where repeated shutdowns before wallet catchup
results in never receiving first run credits
-fix settings to write new defaults that aren’t already in the
configuration file
-report log of startup sequence if upload_log set to true
-redirect /view?name=lbry to the main UI page. This is to make the ui
accessible from a lbry:// link on linux
-adds is_lagging indicator as a key from daemon_status, which is set to
True during a phase of the startup sequence, presently only during
loading_wallet if catching up with the blockchain takes longer than a
minute.
-checks if connected to internet before trying to start
-calling help() will return the list of functions
-setting the ‘function’ param in the help function will return the doc
string for that function
-setting the ‘callable_on_startup’ in the help function will return the
list of functions callable during the startup sequence
-adds version() function, which can be called after the daemon is
running and returns lbrynet, lbryum, and lbry ui version information.
-daemon_status now returns how far behind its behind the blockchain
when in the loading_wallet phase of startup
-cleans up set_vars by moving to init
