#lang filetype detection is harmful about vim-racket HOT 2 OPEN

This is at least partially my fault; I advocated for this on the basis that not all *rkt files are actually racket, and the racket syntax shouldn't try to highlight them all.

OTOH, br is now correctly mapped to racket, and it's trivial to add sicp/etc. (My fork adds, for example, info and info/setuptab, which it supports. My fork also supports the new jsond language, but it doesn't need extra configuration precisely because of the new mechanism.)

See g:racket_hash_lang_dict in ftdetect/racket.vim. It would be nicer to merge the user's config with the defaults, but I didn't do that yet as I haven't needed it.

I've pushed a commit in my fork which supports user overriding much easier. Simply let g:racket_hash_lang_dict = … to install your own overrides, which are merged with some reasonable defaults (user values take precedence).
