Title: Allow unicode letters in identifiers

Hey Anton!

This patch is re issue #301.

I’m writing an law-specialized app and I’ve chosen to write them in Romanian because it would have been more difficult to translate the domain terms. :o) This is the reason why I need jshint to validate my code with Unicode letters in identifiers.

So here is what I did:

Picked the hex codes for the Unicode 'Letter, Uppercase' and 'Letter, Lowercase' categories from [fileformat.info](http://www.fileformat.info/info/unicode/category/index.htm). However, because I could not find a way to encode 5-digit ([ECMA allows only 4](http://es5.github.com/#x7.8.4)) Unicode escape sequence, I had to leave out 1016 out of 3192 Unicode letters.

Please take a look and let me know what you think.
