Comment 8 for bug 1399190

I'd stay away from the BAMF like matching... I mean I've been doing it, and it's not 100% reliable.
While it might be nice at development time, it shouldn't be allowed in production imho.

What probably we should support, is an environment variable and not just a "--desktop_file_hint" thing, that might also break some non-ubuntu-touch native apps args parsing.
