Change the library servlet to print out its location on both the sample
app and the playground.
ActivityStream works on w3 (but not the side nav for now, so multiple
views will not work) , 4.0 and 4.5. 

Added method in util for spliting a query into an object.
Add my url class. The url class is finished but validation needs to be
added to each of the set methods, with errors etc.
These util classes aren't needed any more... At least we validate input
in the set methods.
Use url class in _sbtAsConfigUtil instead of the old local / worse
regexp... Bit better private doc in url.
typo
No need for the comment about setting any more.
