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.

The cache does not remember match length but next position after the match.
...
This leads to simpler and faster code because it avoids one addition and
subtraction.

Changed order of parameters in the SyntaxError constructor to make creating error with unknown location easier. Also fixes bug with reporting of invalid ranges such as [b-a] in the metagrammar.

Do not recognize \uFEFF as whitespace in the metagrammar since it does not work with Rhino.
