Replace $() usage with OpenLayers.Util.getElement()

[euzuro]

Found a couple of places where this has crept back into the code.

this fixes all the $()s that I could find. Most of them are in the examples but a couple of them in the lib dir as well. I've run tests on FF and IE6 and they pass. Also reasonable passingness on Opera/Mozilla (they break on the same tests as trunk).

[euzuro]

it might be a good thing to go through and open those examples, make sure they pass. im not familiar with them enough to tell if stuff is working or not. (acceptance tests / examples reform -- hoorah!)

[openlayers]

What is the official policy here? I can't find any reference to the rule.

ok, please commit this - then I'm submitting a patch that gets rid off all occurrences of its use - in favor of document.getElementById - no reason to hide what's going on here - since we are always calling it with one argument

[tschaub]

I'd say the rule is to use document.getElementById unless you want to return an array of elements
