Better in-app browser support

It would be nice for hyperPad (in-app) browser to have better support.

One huge example, downloading shared project links.
If you try, it will say there's a connection error - Also a minor glitch, when pressing back the "connection error" text will still be present on the loaded webpage.

So we have to copy the link, open it in an external browser, then press "open in hyperPad". This could be a way smoother experience if it was directly supported in the hyperPad browser.

I think there's also some other file types that give a connection error too, but I'm not sure.

Yeah, these little fixes are needed. :D
