in allowed HTML tags, attributes with hyphens are parsed incorrectly

In HTML 5, custom data attributes are allowed. They take the form of [data-foo="bar"]. Pear Wiki does not take this into account, and your markup will be screwed up if you use attributes with hyphens.

The solution is in changing the regular expression on pearwiki_filter/parse_override/parse/Ignorehtml.php on line 32, from:

  var $regex = '#</?\w+(\s+\w+="[^"]*")*?/?>#';

To:

  var $regex = '#</?\w+(\s+[-\w]+="[^"]*")*?/?>#';

I hope it helps!
