Massive commit discussed before the freeze to move the PostScript initialization

files to Resource/Init. This obviates the need for geninit when COMPILE_INITS=1.
A followup change will enhance mkromfs to allow it to 'strip' comments and white
space from PostScript input files somewhat reducing the compressed storage needed
for the files in Resource/Init. All files mentioned in int.mak with 'ADDMOD ...
-ps ...' are included as well as those that would have been included via gs_init.ps
%% Replace lines.

Builds tested on Windows and Cygwin for the various executables (gs, pcl6, pspcl6
and gxps).

The default LIBPATH and GenericResourceDir are adjusted accordingly.
