Log Message:
-----------
SCI: Started rewriting file handling. Warning: This will likely introduce
regressions, but we just have to start somewhere.
- factored out some common code in engine/kfile.cpp into a separate func
- replaced many uses of chdir, getcwd, sci_init_dir etc. by equivalent
or better functionality from SearchMan etc.
- replaced many uses of sci_open and sci_fopen by using Common::File
and Common::Stream
- C++ified some stuff
- simplified ResourceSource a bit (loosing some unused functionality)
