Investigate Prototype + OpenLayers interactions in IE, Opera

[crschmidt]

We haven't actually done any serious testing of prototype libraries with OpenLayers in the page. We need to start doing this, and making it part of our testing, because we're getting reports of serious problems in this regard.

one stack trace, for example:

(In [4324]) Add directory for prototype-based testing. Add content from  http://cakebox.net/osm-slippy-test/map.html to start working on reproducing the problem. (Thanks, bobkare.) (See #977)

I've been playing, and with 2.5, I've been unable to cause problems. Can anyone else confirm/deny that they have something that does/doesn't work?
