Preparation of hooking up the new preprocessor.
- Added custom Diagnostics class. Routed all info-log messages via this new class.
- Added custom DirectiveHandler class. Moved directive-handling code to this class and routed the old path.
- Deleted lexer_glue because it is not needed anymore. The new preprocessor is almost ready!
- Killed a bunch of dead code related to PragmaTable.
