Add query_params to static_caching.exclude

[indykoning]

Currently you can only exclude items from cache using a custom class, Urls or url regexes.
However these regexes are run on the url with the url parameters stripped.

This means if query params are enabled pages like /search?q=test or /page?nocache will be cached.
This could create a large amount of caches for pages used once.

I propose adding query_params to static_caching.exclude, if the url contains one of these query params. caching will be disabled entirely, just like the urls works.

(as a default we could add live-preview)
