Add WordPress Required Version and Tested Up To Version for themes

[cais]

The premise of this idea is for Theme authors to be able to add a reference to the version of WordPress their Theme requires to work correctly; and, the version of WordPress the Theme has been tested up to. This idea comes from the the plugin readme.txt file and some of the data that is expected to be found there.

Once implemented, further enhancements to the Appearance tab in the Administration Panels can be added to better inform end-users on the compatibility of the Theme with their current WordPress installation.

Updated ... not sure what happened with the first version. Sorry for the inconvenience.

There's a checkbox to overwrite files of the same name, you probably just didn't rename the file?

Updated the patch ... needs testing, but should accomplish the same goals as the original patch did when it was submitted.

Update to original patch; name changed to keep original patch for reference

Tested the new patch with trunk; everything works as I'd expect and I'm able to get/display the new headers.

Supported/required versions would be a major help to WPTRT: even with just what we see here, having an officially-supported way for authors to specify the information would be terrific, but more importantly, it gives us the ability to add functionality to theme-check, work towards getting automatic checks into future versions of the installer, etc.
