Renaming Nepomuk-KDE

[Sebastian Trüg]

Hi guys,

it seems that it is quite hard to find a new name. I personally don't like 
Tenor or Braid.

So I propose I do the following on this beautiful Monday:
merge knepomuk, kmetadata, and konto in one "nepomuk" folder in kdelibs to 
reduce the number of libs. Then merge KMetaData and Konto in one 
namespace "Nepomuk" and put KNepomuk into namespace Nepomuk::Middleware.

In the end, the name nepomuk is not that bad and my "bosses" will be very 
happy that we reuse their name. ;)

I will do this merge now, regardless of the name "Nepomuk". It can be changed 
easily using sed afterwards.

Cheers,
Sebastian
