Review swaps

[Chen Lei]

I've have several review requests that have been sitting around for a while
now.  Many of them are new dependencies for existing packages in
fedora, anyone want to swap?

EmfEngine(new dep for qtiplot 0.9.8.1):
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=618480

libqmf (dep for qt-mobility):
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=626122

contextkit(optional dep for qt-mobility):
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=613881

libqttracker(optional dep for qt-mobility):
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=614075
