Better NACK handling when pushing new presets.
Added NACK handling to sending ETA
Delete wscript
Update README.md
Switched from ints for IDs to Strings
Only displays presets now.

Updated to v1.1.0 with a slightly different app flow. Now instead of displaying "PRESET #X" when there are unset presets, the app simply passes over that preset slot. Also displays a "No Presets Set" display when there are no available presets. Additionally, added an error screen for when the application detects that persistant storage is broken on the watch.
Merge branch 'release-1.1.0'
