Frameworks and GRASS.app, yet again

I hope you’re not getting tired of the updates. ^_^

GRASS.app updated to latest CVS.

Many small framework updates. A big one is extra GDAL plugins can now be installed in /Library/Application Support/GDAL/PlugIns, or the same in your home folder. This keeps addon plugins safe from GDAL framework updates. Also, GD and PDFlib added as frameworks – getting ready to update PHP and MapServer.
