Subject: [PATCH] * Discarded extra deflate function needed for afm reading -
 as a result, discarded the whole chain of support functions, .c files and
 includes needed to make that one function run - also removed zlib
 compile/link dependencies where they are not needed - reduced the whole zlib
 package into two core include files - adjusted makefiles / project files to
 reflect this change
