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.
