Script to convert pfSense config XML to OPNsense

[juliocbc]

Hi folks!

We're using a small piece of code to help us to convert from pfSense to OPNsense XML config file. It's still in a beta stage, but we're achieving good results with it.

There are known issues that should be corrected/improved. Contributors are very welcome!  ;)

Tested with XML files from pfSense 2.1.X and 2.2.X versions.
