Minor license header issue

[Adriaan de Groot]

I was pointed to a minor issue with license headers in some files in Amarok. 
Not all the files have license headers (GPL, LGPL or otherwise). Take a look at

http://gitweb.kde.org/amarok.git/tree/05663d4e37e86263a3471071a9f3cd7c0bbdcbb2:/src/core-
impl/collections/mediadevicecollection/podcast 

the files there have no license header. Although they're small and almost 
trivial, they should still have a header. Stecchino tells me the files are 
unused and could be removed instead of having a license header added.

The GPL header from, say, 
http://gitweb.kde.org/amarok.git/blob/05663d4e37e86263a3471071a9f3cd7c0bbdcbb2:/src/core-
impl/collections/mediadevicecollection/MediaDeviceCollection.h would do.

One comment on the license header in that file is that although the license is 
GPLv2+, the header points to a very generic gnu.org page which currently 
mostly talks about GPLv3. That might be improved by pointing to the older v2 
license *and* the generic page.
