Changed a lot of platform-specific code to "simplify" it:

A Unix-like system is now considered the default.
The number of platform-specific blocks is down to:
   win32: 13, watcomc: 3, linux: 4, macosx: 16, amigaos4: 8, beos/haiku: 1
Removed linux.c, implemented the relevant functions for all platforms.
(win32) In Stats screen, included free memory report
(macosx) Conversion_ANSI: Fixed the __macosx__ with wrong case from my former 'fix', sorry.
(macosx) readline.c : Removed a manual "Update_necessaire=1", because normally
all calls to UpdateRect() will set this flag already. Don't hesitate to call 
Flush_Update() anywhere where it's lacking, but you shouldn't put it inside a  #ifdef __macosx__
(win32) Packaging: 'make ziprelease' now includes libpng13.dll and zlib1.dll
(win32) Hacked something to resolve naming conflict of MOD_SHIFT constants with windows.h
(all) Resolution: Fixed the black space that appeared between button and label,
the memory overwrite also caused resolutions above number 2 to disappear from list.
 
Tested fine on Linux (without TTF) and Windows
