DUB 0.9.14/0.9.15 has been released

[Sönke Ludwig]

Two additional notes:

 - There is a known bug that causes multiple DUB invocations to be
   required until all indirect dependencies are installed (watch out
   for a "There are still some actions to perform:" message). The
   current git master fixes that.

 - The "-property" switch has been disabled, considering that the
   general consensus of the property discussions was to allow dropping
   parenthesis on normal functions.
