Battery life improvements

[Katharine]

Hi there!

We have noticed that Futura Weather can exhibit some behaviour that causes moderate or severe reductions in watch battery life. This PR aims to fix those.

In particular, this PR:

• Does not reload the weather image from flash every second
• Only updates the displayed weather information when it actually changes, instead of every clock tick
• Does not get stuck in a retry loop that kills the battery in under a day when disconnected
• Reduces the tick interval from once per second to once per minute
• Makes use of the bluetooth service for retries and icon display
• Simplifies some logic

Please take a look and merge.

Thanks! :D

Can I assume the version in the Pebble Store has those fixes implemented?

Thanks Katharine!

@Katharine – I'm confused; did you guys just replace @Niknam's watchface with your own fork of it on the Pebble watchapp store?

[Katharine]

Yes. We asked first.

[lepinsk]

Ah, that makes sense. :-)

Do note that due to an appstore bug, updating an app actually requires that you unload it from your watch, remove it from your locker, and add it back from the appstore page.

You may find this hard to do due to another appstore bug that sometimes breaks removing apps from your locker (sigh…).

We are working on a way of fixing this both for the special case of Futura Weather, as well as globally.
