New functionality to use installation information from the Windows registry. This allows you, for example, to instruct ExcelPython to use the default Python 2 installation even if Python 3 takes precedence according to the system path.

• New macros are available in xlpython.cfg providing the folder of each Python version installed and registered as default, as contained in the Windows registry. Further information is available in the docs.
• It is now possibile to include a trailing slash within macro parentheses, for example like so: $(?Registry:Python2Folder\)python.exe. This means that if the macro is not defined the string will simply resolve to python.exe and not \python.exe as it would were the slash outside the macro parentheses.
• Small bug fix related to reloading config files.
