iOS Share Sheets

Current work in progress share sheet

I have found the lack of a share sheet  in iOS and OSX limits how much I use Monal.  A lot of what I send in chats are links. I suspect that is the case for a lot of other people too. To address that, I’ve added a share sheet to the iOS client. This code should work on OSX too.  Doesn’t quite work yet but when it’s done, will work the way you expect it to.
