fixes#1231
Motivation
----------
Previously when messages failed to send, there was no reason given.
Furthermore, when media messages failed to send there was no indication
that any attempt to send the message even occurred, nor a retry
dialog.
UX Changes
----------
- Show "uploading" status for media
- Show specific error message in retry-send dialog
- Only scroll to bottom when new message is inserted
- Show specific errors when group creation fails
Code Changes
-----------
- Updated incorrect references to TSMessageAdapters which were actually
references to OWSMessageData
- MessageSender was extracted from SSK MessagesManager
- access MessagesManager as property
- idiomatic init/properties for Env
- log contact intersections
- Move scroll-to-bottom animation to main thread.

* Per thread settings menu accessed by tapping on thread title
This removed the toggle-phone behavior. You'll be able to see the phone
number in the settings table view.
This removed the "add contact" functionality, although it was already
broken for ios>=9 (which is basically everybody).
The group actions menu was absorbed into this screen
* Added a confirm alert to leave group (fixes#938)
* New Translation Strings
* Extend "Add People" label to fit translations.
* resolved issues with translations not fitting in group menu
* Fix the long standing type warning where TSCalls were assigned to a TSMessageAdapter.
* Can delete info messages
Follow the JSQMVC pattern and put UIResponder-able content in the
messageBubbleContainer. This gives us more functionality *and* allows us
to delete some code. yay!
It's still not yet possible to delete phone messages. =(
* Fixed some compiler warnings.
* xcode8 touching storyboard. So long xcode7!
* Fixup multiline info messages.
We were seeing info messages like "You set disappearing message timer to
10" instead of "You set disappearing message timer to 10 seconds."
Admittedly this isn't a very good fix, as now one liners feel like they
have too much padding.
If the message is well over one line, we were wrapping properly, but
there's a problem when the message is *just barely* two lines, the cell
height grows, but the label still thinks it's just one line (as evinced
by the one line appearing in the center of the label frame. The result
being that the last word of the label is cropped.
* Disable group actions after leaving group.
