* Added BTextView derived class HyperTextView, which allows for

Browse Source 
associating text with an action performed when clicked. Very
  bare-bones, but sufficient for our purposes.
* Turned all URLs into proper URLs (i.e. prepended "http://" where
  missing).
* Added new AboutView::AddCopyrightEntry() versions. One can take an
  additional licenses list, the other extracts all info from a supplied
  BMessage.
* The displayed licenses and URLs are hyperlinks now. Clicking the
  former opens the license file in /etc/licenses, the latter try to open
  a browser (works with NetPositive at least).
* The "COPYRIGHTS" attribute of the executable can contain descriptions
  of optional packages. Those are read, parsed, and added as copyright
  entries.
