/*!
   \brief initialization of the eclass manager
   general guidelines about eclass.cpp implementation:
   - we don't support unlimited number of eclass file formats together
   currently limited to two
   support for .def is builtin to the core, but you may choose not to activate it
   - search and load of the files:
   the manager is in charge of scanning for eclass definition files to load
   there is a general configuration setting for games which use a different set of
    entities between single player mode and multiplayer mode (TODO: the code doing
    this needs to be abstracted some more)
   - duplicate files / multiple files:
   if two files with the same name exist (for instance in the basegame, and in fs_game)
   then only the first one found in the scan order is loaded
   if several files are found, they are all loaded
   this allows mods to either replace or extend the list of eclass
   - if eclass_singleload prop is used in the .game, then there is no multiple files check
   the first file found is loaded, and there is no further search for the given extension
   (this was an addition for HL support)
