New Share / open in methods

Change iOS share to use `presentOptionsMenuFromRect:inView:animated:` instead of an `UIActivityViewController`

View also falls back to `presentOptionsMenuFromRect:inView:animated:` if the file cannot be previewed.

Fixes SpiderOak/SpiderOakMobileClient#448 and others (at least on iOS)
