iOS: allow swiping left to right to go back

[prabirshrestha]

When viewing a single notification, swiping left to right should be equivalent to back button. This is common gesture for majority of the iOS apps. I found it cumbersome to click the back button at the top in the header.

Mail and Safari on the phone are some examples this.

I agree, good find. I think this has something to do with the custom navigation thingy I had to do. Thanks for reporting.
