Minor default config refinements.
Setup new "loader" module prototype and removed unused "getUser()" function.
Moved to using JSON for configuration instead of JS files. Put more work into separate "loader" module architecture.
Config: Moved "roomURL" and "reloadAfterMinutes" to JSON configuration file.
Removed unnecessary require() statements and unused external modules.
Fixed reference error in main getAPI() function. Other notes and reorganizing.
