Add example using mingw

 .gitignore has added .idea/ to avoid checking in Clion project files

 README.md has got a description of how to build for mingw

 source/CMakeLists.txt has got one more platform, and the compiler options
 are added to avoid warnings from the gcc compiler.

 doublylinkedlist.c has got an added #include nedded when no tracing is
 enabled to avoid undefined NULL constant.

 The rest is the application. ConfigureNetworkInterface() is modified to
 ues the IP address as parameter, so the
 opener.exe can be started with ip address as argument and not interface
 number. The windows version also has
 several errors and could not be compiled. The
 DEMO_APP_CONFIG_ASSEMBLY_NUM has been changed from 151 to 1 in order
 to be tested against my PLS.

+Compile for MinGW on Windows 10
+-------------------------------
+1. Make sure 64 bit mingw is installed. (Test with gcc --version, should show x86_64-posix-seh-rev1)
+2. Make sure Cmake is installed. (Test with cmake --version, should be version 3.xx)
+3. Change to <opener install dir>/bin/mingw
+4. Run the command `setup_mingw.bat` in a dos command line. (Not a bash shell). If tracing is desired, 
+use the following (where the cmake parameter must be enclosed in quotes) or change the ./source/CMakeList.txt file.
+    ```
+    setup_mingw.bat "-DOpENer_TRACES:BOOL=TRUE"
+    ```
+5. Run the command "make" from the same directory (./bin/mingw)
+6. The opener.exe is now found in <opener install dir>\bin\mingw\src\ports\MINGW
+7. Start it like this: "opener 192.168.250.22", where the ip address is the local computer's address on the nettwork you want to use.
