[Freewx-maint] Bug#738849: Please enable webview support for wx3.0

Hi again Olly.

The package seems to be building fine, running with the split and boinc now builds correctly (I didn't test the run, just the build).

I double checked the libraries, they aren't anymore in the gtk package and they are in the webview one.

I also checked the documentation, and updated it.

I'm still a little bit worried about the dependencies that I should add for the new packages, can you please review?

The patch was really trivial, it needed just a little time for me once I got the courage for starting
Nothing should be pushed upstream, the package already correctly builds its own library.

I would like to contribute a little more if you want, bumping standard version, maybe cherry-pick the patch from #736374 or would you like to wait for the new upcoming release?

I really would like a positive, negative or whatever feedback (please ask me to test whatever you want, I don't know if I did the whole work correctly)

have a nice weekend
