dmg names

Currently we have MacPorts-1.5.0-10.3.dmg MacPorts-1.5.0-10.4.dmg MacPorts-1.5.0-10.5.dmg These names are rather similar and people have in the past not realized that these are for different OS versions. Maybe we could use the kitty name starting with our next release? MacPorts-1.6.0-Panther.dmg MacPorts-1.6.0-Tiger.dmg MacPorts-1.6.0-Leopard.dmg That would make it easier to distinguish between the different images. Note that Apple has been using this kind of naming for some time already in its security updates, and now also in the QuickTime 7.3 disk images.
