Remove unstaged devel/semantic and two of it's unstaged dependencies
Remove unstaged tcl/tk 8.0 and two affected staged ports

The two ports affected by the tcl/tk 8.0 removal, ja/tkhonyaku and
ja/timidity++-tcltk only build on FreeBSD 8.x because the tcl/tk ports
themselves don't build on FreeBSD 9 and later.  The timidity port was
staged but unmaintained, and the tkhonyaku port was staged by its
maintainer who was advised that his port was in danger of being removed
with tcl/tk 8.0 at least 3 weeks ago.
deskutils/gnotime basically contains two ports.  Split off one part into
a new port databases/qof:

QOF - Query Object Framework - library to add a query engine to C
applications with generic XML backend.  A SQL database is not needed; any
collection of C/C++ objects can act as tables.
