Title: Show URLs have children, don't show text has children

Previously, text was set to return YES for `objectHasChildren` meaning there was always a small '>' arrow next to text objects.

In the same manner, URLs were also set to return NO for `objectHasChildren` so the '>' would never show for URLs.

Regarding the URLs - I have added the `objectHasChildren` method, which checks if the URL has a corresponding `QSURLParser` available for it.
If it does, then it saves the `type` of URL parser in the object's meta for easy collection later on. Otherwise, it would be required to iterate through all the .tlds again to find the type.
