Removing the KFileMetadataWidget

[Vishesh Handa]

Hello people

The current KFileMetaDataWidget uses the Nepomuk libraries which no longer 
exist in kdelibs. So when we finally start splitting the libraries into their 
own git repos, kde4support will detect that Nepomuk is not installed and that 
will make KFileMetaDataWidget useless - It literally will not do anything.

I'm planning on removing KFileMetaDataWidget completely, and marking it as 
deprecated in kdelibs4. Applications which still use it (Konversation and 
KGet) can start using Nepomuk::FileMetaDataWidget which offers the same api.

Objections?
