Lots of places where coders did not realize our Printer::log with hint adds a ": " string between message and hint
Which caused uglier messages in a few places (added documentation for that, maybe helps?)
Some added info in a few places
Some whitespace unification
Some spelling unification

C++ has undefined behavior for identifiers starting with __ or with _ followed by an uppercase letter.
We still have many more (in IrrCompileConfig.h and in all header-guards), will likely replace those later as well.
As a workaround for users which might use irrlicht defines in their code, I've added the header irrLegacyDefines.h
Including that allows to continue using old defines for a while - or make it easier to have code which compiles
with old and new Irrlicht library versions.
