Summary:
Ref T2700. Allow JS to listen for swipes on devices.
There are a bunch of tricky cases here and I probably didn't get them all totally right, but this interaction broadly looks like this:
- We implement gesture recognition for the mouse in device modes (narrow browser), and for touch events from an actual device.
- The sigil `touchable` indicates that a node wants to react to touch events.
- When the user touches a `touchable` node, we start listening for moves. They might be tapping/clicking (in which case we don't care), but they might also be gesturing.
- Once the user moves their finger/pointer far enough away from the tap origin, we recognize it as a gesture. I hardcoded this at 20px; I wasn't able to find any "official" Apple value, but 20px seems like a common default.
- At this point, we look at where their finger has moved.
- If they moved it mostly up/down, we interpret the gesture as "scroll" and just stop listening. The device does its own thing.
- However, if they moved it mostly left/right, we interpret it as a "swipe". We start killing the moves so the device doesn't scroll.
- Once we've recognized that a gesture is underway, we send a "gesture.swipe.start" event and then "gesture.swipe.move" events for every move.
- When the user ends the gesture, we send "gesture.swipe.end".
- If the user cancels the gesture (currently, only by tapping with a second finger), we send "gesture.swipe.cancel".
- Gesture events have raw position data and some convenience fields.
Test Plan:
Wrote UI example and used it from the Desktop, iPhone simulator, and a real iphone.
- The code always seems to get "scroll" vs "swipe" correct (i.e., consistent with my intentions).
- The threshold feels pretty good to me.
- Tapping with a second finger cancels the action.

Summary:
Currently, you can't change a notification that's already shown. There's no reason for this.
(I'm planning to put file upload progress/errors in notifications.)
- Make `setContent()` and `setDuration()` immediately affect the notification.
- When there are more than 5 notifications, queue them up instead of dropping them.
- Allow arbitrarily many classes to be added/removed.
- Make the examples in the UIExamples tests more rich.
Test Plan:
- Verified normal notifications continue to function as expected.
- Played with the UIExamples notifications:
- Verified the "update every second" notification udpated every second.
- Verified the permanent alert notification was yellow and requires a click to dismiss.
- Verified the interactive notification responds correctly to "OK" / "Cancel".
- Verified the "click every 2 seconds" notification doesn't vanish until not clicked for 2 seconds.
