version number bump. Yeah, well, it took me a bit to even get it
to compile, one of those, "Hey, let's change the entire build
infrastructure for a minor bugfix!" things...
But hey now we're fully in-sync with Gnome 2.6.2.
ORBit2 2.6.3 -> 2.8.1
gconf2 2.2.1 -> 2.4.0.1
libgtop2 2.0.2 -> 2.0.5
libwnck 2.2.2 -> 2.4.0.1
vte 0.10.29 -> 0.11.10
Also removes devel/linc since it has been rolled into devel/ORBit2.
