Compatibility with sdk 1.4

All unit tests pass now, also in Windows. 

One must be careful when compiling the SDK: see changelog:

- By default, the UAF is now compiled *with* HTTPS support. However, if your Stack and SDK were 
  built *without* HTTPS support, you must (!!!) also compile the UAF *without* HTTPS support.
  See the install_linux.rst.txt and install_windows.rst.txt files for more info.
