Forward slash RegEx bug

When matching for domains without a last forward slash on the address

Well… seems that my RegEx extension has a bug.
But, then again: there is no such thing as a sloppy fix if it really is
a fix.
First glance on asynchronous requests

Using low level Grand Central Dispatch #GCD and a serial and parallel
array the activities of the parser have been queued outside the UI
thread for responsiveness while using the framework.
