Work more on parser

This does more work on the parser, including moving from the old
LineReader/Scanner combo to BlockReader.

It includes more syntax checking, but still doesn't actually do anything.

With some dummy methods in RGrammarBuilder, should be able to see if the
basic file parser is working correctly.

Where blocks and their syntax still need to implemented, and actual pragma
implementations need to be provided.
