First release

I revived this old plugin for some controller actions that are paginated and contained 100+ URLs with quite some custom routing going on.
The speed improvement was immense in this case: More than 10x faster with the 2nd page load.

In other cases this might not be that much, but with not too dynamic views and a lot of generated URLs the improvement is usually quite good none the less.

This initial release also contains a DebugKit toolbar panel for easier debugging of this URL caching.
