Markup spec/ANTLR

I will henceforth be describing the wikitext grammar uniquely in ANTLR format, which has many advantages. Primarily it can be readily validated right now using ANTLR or ANTLRWorks.

Currently "promising vaporware".


 * Good: ANTLR grammar looks capable of describing much more of MediaWiki wikitext than EBNF.
 * Bad:
 * ANTLR doesn't yet render to PHP.
 * ANTLR's generated Java is huge and slow.
 * ANTLR is buggy.
