Android app: make share intent add site to app, not launch web app

[jancborchardt]

Currently when using the Firefox share menu to add sites to Poche, the web interface is opened.

This is strange since the intent comes from the app. Also it's annoying since I want to either continue reading the page or close it - Poche should not distract the flow.

Hence, the link should rather be added to the Poche app in the background. with just a vanishing notification that it did so, much like Pocket does.

Should be OK with poche v2.
Actually I need to open it in Web Browser because of the authentication method.

@nicosomb @vjousse any timeline on Poche v2 by the way? This one and #115 (staying connected) are the top most annyoing problems which hamper everyday usage.
