Pebble Time ready.
Timer now uses wakeup API to relaunch the app 5 seconds before end if the app was closed while a timer is running.
New color scheme on pebble time ("match watch") which uses a background color matching the watch color as close as possible.State is saved when app is closed. If a timer was running, it is resumed on restart as if the timer were running in background.
Note: the timer actually doesn't run in background, because this is not possible. So if the time runs out while the app is closed, nothing happens.
