/**
* API: CORE
*
* This class deals with all core functions.
* This class deals with all available language functions.
* If $ipsclass is passed to it, then it will skip the init
* However, if $ipsclass is not an object, it'll initialize
* the $ipsclass object, and by default load all the required
* IPB classes and init them (DB, converge, forums, display, session)
* and it'll also get a new DB connection and load settings and caches.
* You can alter which classes are loaded via the $this->load_classes[-class-] = 1;
* array
