mozilla-nss is dead, long live nss

[Christopher Aillon]

Just a note that mozilla-nss is no longer in the tree.

Packages should depend on nss instead, and nss-devel for building.  I've 
rebuilt evolution and xmlsec1 already to support this. 
Note that there is now a version jump.  NSS is currently at v3.11 (and 
NSPR is at 4.6), so packages which checked for mozilla-nss >= 1.x should 
also update their version checks (nss 1.x would not be usable).

Bug reports go in bugzilla.
