Support full range of allowed IDs in HTML5

Description

HTML5 seems to legalise all non-space characters for ID strings.

This creates a situation where you can have IDs which jQuery cannot match because its 'quickExpr' regular expression matches according to the more restrictive HTML4 standard.

See  http://jsfiddle.net/2Zpn4/4/ for an example showing that document.getElementByID can return elements which JQuery cannot match.

  • Priority changed from undecided to high
  • Component changed from unfiled to selector

the /TR/ spec pages should not be used as reference as they are considered "trash" and exist only for record

The correct reference would be:

 http://www.whatwg.org/specs/web-apps/current-work/multipage/elements.html#the-id-attribute

As a note, attribute selectors _do_ work here:

  • Status changed from new to closed
  • Resolution set to invalid

Just need to escape the special chars.

Please follow the  bug reporting guidlines and use  jsFiddle when providing test cases and demonstrations instead of pasting the code in the ticket.
