Title: Support for XeTeX 0.9998 and other bug fixes

This pull request include al the changes in the previous one that I just cancelled (text below for reference), plus some bug fixes and features from the issue tracker.

What remains now is how to handle old engines, my own preference it to check for XeTeX ≥ 0.9998 and LuaTeX ≥ 0.70 and print an error message otherwise, supporting older engines is not worth the effort and complication it brings.

>This branch implements support for new math features in the upcoming XeTeX 0.9998 (mostly accents >related) by sharing the same code path as LuaTeX when appropriate. The cone now uses the new features >unconditionally (as it was the case already for LuaTeX, though version check was sometimes done), This >means the package will break with TL 2011 and lower but the code is much simplified (and users of >unicode-math should really upgrade to the new XeTeX anyway).
