Open package installer when opening a received apk file
As an app developer I use Infinit only to quickly send new released apk to my collaborators so they can test it. So far Infinit is the quickest way I found for that. So please just launch the system package installer when opening an apk : this can be achieved by knowing the mime type of the file. This is how File Expert and other file explorer works and we expect Infinit works like that.
