Renamed documentation files to .txt and converted them to DOS line endings so they would open properly on all systems.

Updated Makefile.in so "make dist" includes everything necessary for release.

+
+This is the Simple DirectMedia Layer, a general API that provides low
+level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL,
+and 2D framebuffer across multiple platforms.
+
+The current version supports Windows, Mac OS X, Linux, FreeBSD,
+NetBSD, OpenBSD, BSD/OS, Solaris, iOS, and Android. The code contains
+support for other operating systems but those are not officially supported.
+
+SDL is written in C, but works with C++ natively, and has bindings to
+several other languages, including Ada, C#, Eiffel, Erlang, Euphoria,
+Go, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP,
+Pike, Pliant, Python, Ruby, and Smalltalk.
+
+This library is distributed under the zlib license, which can be found
+in the file "COPYING".
+
+The best way to learn how to use SDL is to check out the header files in
+the "include" subdirectory and the programs in the "test" subdirectory.
+The header files and test programs are well commented and always up to date.
+ore documentation and FAQs are available online at:
+	http://wiki.libsdl.org/
+
+If you need help with the library, or just want to discuss SDL related
+issues, you can join the developers mailing list:

+
+Enjoy!
