This separates the grammar parsing from early error checking. The early error checking (phase two) is now done in an optional reduction. This will allow us to use a parser generator for phase one, and the hand-written recursive descent parser is much more maintainable now.

Fixes #44.
Fixes #56.
Fixes #91.
Fixes #172.
Fixes #177.

I will squash to appropriate commits once the review is completed.
