With implementation to support queries accross the project. REMOVED IN FUTURE VERSIONS

#THIS IS REMOVED FROM FUTURE VERSIONS!
Dispatch queries from anywhere in your project and receive them from a defined listener.

Queries get dispatched one at a time. If a query comes in and there is a outstanding query,
it gets cached and dispatched as soon as the current query gets answered by the user.
Queries get cached if there is no subscriber currently.
There can only be one subscriber for queries.

I were about to implement custom query options but then realized it is basically useless. Queries can be to diverse, which can't be supported in a usefull manner. In the end, the receiver for the queries would put them on screen for the user and send the answer back. But anyone can put a widget to the screen if he needs a answer from the user, thus I just trashed this.

If you are interested in this, it is working, but stopped while implementing custom query options, you would need to continue there.
