1. Move all content from rKGF to rKOT
2. rKGF is at this stage a wrapper for rKOT
3. Upgrade calling code to directly use rKOT
4. Deprecate and archive rKGF
Plan should also solve the dprint_r/dieprint_r issue: there are convenient methods to use as debug time. We should enable a global functions registration (in \ namespace, not in \Keruald) to ease debug with something like "DevUtils::registerGlobalFunctions();".
