New port: emulators/z80pack Z80 emulator with CP/M-80

This port builds only the generic Z80 emulator and installs various
CP/M-80 disk images. The images can be copied into user directories
and updated from within the emulation of with the cpmtools programs.

The emulation covers CP-NET and MP/M-80 and addition to CP/M-1.4,
CP/M-2.2, and CP/M-3.0.

The port could be extended to install the full hardware emulation of
some classic S-100 bus computers from ALTAIR, IMSAI, and Cromemco
(including working emulation of the front panels).

+z80pack emulates an 8080 or Z80 CPU and provides CP/M-80 and UCSD-Pascal
+environments. Besides emulation of a generic CP/M system, support for
+full emulation of typical ALTAIR or IMSAI systems and their specific
+hardware is possible, including a graphical front-panel.
