Add two cmake commands -E echo for echoing strings and -E comspec for workaround of bug of windows 9x; add another implementation of run command on windows which should work...

Several changes: COMPILE_DEFINITIONS is now depricated. If you want to specify some, use CMAKE_FLAGS -DCMAKE_DEFINITIONS:STRING=...; same goes for libraries, include path, ... It now detects wether the file is C or C++ and uses the apropriate project command, it also does the right thing when doing try_compile, so it does not execute configure for every single try_compile

Improve backward compatibility, so that all backward compatibility stuff is in two modules; fix invoking of try_compile; add checking for header files and sizes of types

Some GUI improvements and fix the way dirty is being set, so that if there are no cache values, dirty is not set
