[CMake] CPack Generator jar support

but knowing that a jar file is a zip file subclassing
cmCPackArchiveGenerator.[h|cxx] to cmCPackJARGenerator.[h|cxx]
in the same way
cmCPackZIPGenerator does
should be fairly straightforward.

Then you need to add a test.

If Alexander want to try that I may take the time to review the code.

the real question is:
   Is it of general interest to add such a generator to CPack?
  (no offense to your need Alexander).

By the way did you try the ZIP generator with

set(CPACK_INSTALLED_DIRECTORIES "/path/to/META-INF;/META-INF")

if some local (to the build) directory /path/to/META-INF contains
the appropriate MANIFEST.MF and INDEX.LIST your jar should be built ok
beside the fact it will have the zip extension.
