Fixes for segfaults that happened when vche was called with very large file names, a cosmetic patch for do_exit(), changes in Rules.make, some new free()s in rawlib.c and nclib.c to free undeallocated memory, and a patch to make searches case-sensitive or case-insensitive.
Added the code to edit non-regular files like hard disks, floppies, CDROMs, ZIPs, RAM, and almost any device, some bug fixes, fixed the file position percentage when viewing big files, fixed bug in search.c that made the program loop for ever when a string was partially found near the end of file, used C macros to join the VC/NCURSES/RAW versions.
