Bug#506018: velocity: adds libraries to /usr/share/ant/lib

[Ludovic Claude]

Hi Marcus,

I propose to break the package velocity in 2 parts:
velocity: contains velocity.jar and related stuff
velocity-ant: contains the links to be installed in /usr/share/ant/lib/
for the velocity Ant tasks

The rational is that if you install Velocity, you may not always want to
use the ant tasks, but if you install velocity-ant, then you know that
you will use the ant tasks, and having all the jars in the ant lib
directory means less configuration for you.
