David Majda 3291c70d97 Added \uFEFF (BOM) to the definition of whitespace in the metagrammar. 
The Rhino bug that prevented inclusion of \uFEFF among the whitespace characters
is no longer relevant here because we compile character classes into regexps
now, which avoids the infinite recursion.

David Majda 383c5acaa6 Replaced \xA0 by \u00A0 in the whitespace definition in the metagrammar.

David Majda db616f0b77 Made the "version" variable scope smaller. 15 years ago
David Majda c5cc545209 "rake metaparser" and "rake minify" now always generate the target files. 
Until now, these tasks looked at the file times and generated the target files
only when they were older than the source files. This caused problems when I
mainupulated the lib/metagrammar.* files by hand sometimes, replaced them from
backups after screw-ups, etc.
