SOCIAL-545 WIP Figure out how to configure skylight-specific settings while retaining relevant user settings (login account name, etc.)
converted settings_file.xml to use param block descriptions for easier modification
added session settings file and user session settings file for per-session config overrides

Prior to this, you could get a viewer crash whose ERROR: message said only:
convert_from_llsd<std::string>: Invalid string value
This gave no hint as to *which value* was wrong, or where to go fix it.
Ironically, each convert_from_llsd<> specialization already has the
control_name and LLSD value in hand; added these to each such LL_ERRS message.
