reply all functionality

[tomholub]

currently, we have a reply button. should also add reply all, and differentiate the two.

please follow Gmail: add reply-all under the menu for all messages in thread, and then add the three big reply/reply-all/forward buttons on the very bottom below the last message. Thanks!

I think this task should include #921 too, as currently users don't see when mail has multiple recipients.

Also Gmail app by default triggers reply all, and I didn't find way to reply only for message sender (only by removing other recipients). I think it's because reply all is used more often than just reply, maybe we should use reply button for reply all and add Reply option to message menu?

Assigned that one. Looking into reply/reply all. For me, the default on Gmail app is reply-to-one-person.

I think in Gmail this is configurable.
