Rewrite MDB loading code to support loading .xml, .json or .b64 files. This applies to the default MDB (determined by the version of the game requesting it), or custom MDB if that setting is enabled. To use a custom MDB, enable it in Web UI, then place a custom.json, custom.xml or custom.b64 file in the data/mdb subfolder.
Added several player profile stats to the web UI.
Refactored and cleaned up several functions.
MDB loader now logs the number of loaded songs available to GF and DM.
MDB: Fixed "is_secret" field being ignored (always set to false)
