Revamped CMakeLists.txt
Now version of the package is defined in project() directive on line 2. Removed WITH_STATIC option. Now static lib is being linked every time, but compilation of source files is performed only once (google for CMake OBJECT targets) Defined docopt_SOURCES and docopt_HEADERS more explicitly. Now docopt supports installing as "CMake native package", enabling its install system-wide.
