Light refactor of daemon settings processing

- Rename the daemon setter/getter methods to lbry.getDaemonSettings()
   and lbry.setDaemonSettings() to differentiate them from the new
   methods for client settings
 - Add lbry.setDaemonSetting(), for changing individual daemon settings
   easy to
 - Refactor Settings page to submit only changed settings instead of
   re-submitting all settings every time
