hydrogen-drumkits package

[trebmuh at tuxfamily.org]

Hi all,

Reading at this discussion, I'd just want to mention that dispite this 
package is called "hydrogen-drumkits", it does install other stuffs as 
well, demo songs in circumstances.

If you guys are working around this package, it might be the right time 
to switch it to "hydrogen-data-extra" or something around this line.

Leaving this thought to your wisdom now,
best,
Olivier
