Update QT2 to 2.2.4: Re-add USE_MESA, remove antialiasing patch, remove
default -j2 (but keep MAKE_JOBS var), restore old perl REs as soon as I'd
learned how to do multiple ones, remove QPL license file from packaging, sync
with newest KOI8-U/R stuff (not tested). The biggest bonus: split QT
Designer into its own port, and make the qt22/qt-designer pair a member of the
master-slave ports legion, hopefully to reduce redundancy as much as possible.
This should also save roughly 20 minutes of compile time on a dual PIII-600
for those that don't need or want QT Designer. UIC is, however, still
installed/compiled by the default Qt 2.2.4 (as it _is_ required for other
things e.g. KDE2).
