-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
