make bdinfo play nicer with mono

[sjpotter]

Currently bdinfo works basically perfect with mono, except for one issue. the file picker. i.e. click on either file pickers and it crashes out because no WPF in mono.

while I can still use it perfectly (mono BDInfo.exe "path to dir or iso"), it seems a waste to not work perfectly on platforms mono supports because one is using WPF for the file picker. It would seem that there must be a more cross platform mechanism for just that functionality?

I am currently looking into porting the application over to .NET Core, which should increase the compatibility with Mono
