[OpenLayers-Dev] The dot in the ID name difficults jQuery integration

[Tim Schaub]

I agree this is something that should be addressed.  The dots in
element ids has bugged me for a long time as well.  Here's a commit
that is a first step toward correcting things:

https://github.com/tschaub/openlayers/commit/53059408084074903212abd4bf7995b3ad4fb0a6

I'll issue a pull request when I make some time to address a couple
remaining test failures.

I am curious why you'd be trying to access the dom element used to
render a feature though.  This is something I'd consider unsupported
(it won't work with the renderer abstraction in a cross-browser way).
Depending on your use case, there's likely a better way to handle
interaction or rendered feature access.
