Revised FuckBrainfuck Documentation

The current version of the FBF compiler is 1.7.0 and came along with the second revision of its documentation. I recently noticed that the documentation was full of mistakes and I also had forgotten to list some commands so I corrected it and now you can download the zipfile with the new documentation. The zipfile contains the compiler, the documentation, seven example programs and the Lua interpreter for Windows and Linux which is needed in order to run the FBF compiler.
