Changes to the Kile ebuild

Hi there,

I noticed recently that app-text/acroread has been added
as a runtime dependency to Kile. To be honest, I am not 
familiar with the intricacies fo writing Ebuilds, but I can't
see a good reason why Kile should depend on acroread, when
okular or some other PDF-viewer is available. Perhaps someone
can shed some light on this.

Cheers,
