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.

Replaced \xA0 by \u00A0 in the whitespace definition in the metagrammar.

This is purely stylistic change.

"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.
