[Feature] Add AppleScript support

[Schlaubischlump]

Allow the application to be controller via AppleScript. It should provide an abstraction for devices (or at least the currently selected device) and allow navigation, teleportation to a specific location. The menu items should be exposed to AppleScript as well.

[Schlaubischlump]

Remote controlling the App UI is still not possible, but basic support for headless interaction has been added.

Coordinate Suite

methods:

• [x] route from: {lat, lon} to: {lat, lon}: {{lat1, lon1}, {lat2, lon2}, …}

Map Suite

window: class

attributes:

• [x] selected device: device (r/w)
• [x] map: Map (or missing value if no selection)
• [x] move type: enum (r/w) (walk, drive, cycle)
• [x] map type: enum (r/w) (explore, satellite, hybrid)
• [x] speed: real (r/w) (in km/h)
• [x] sidebar is collapsed (r/w): boolean - [ ] request speed change (show ui and return new speed value to apple script. Do not update the UI!)

map: class

attributes:

• [x] heading: real (r/w)
• [x] autofocus: boolean (r/w)
• [x] autoreverse: boolean (r/w)
• [x] automove: boolean (r/w)
• [x] location: {lat, lon} (r/w) (do not ask for user input)

  methods:

• [x] follow route: {{lat1, lon1}, {lat2, lon2}, …} (follow an arbitrary route. You can read a GPX file coordinates from the GPX Suite)
• [x] reset location: boolean
• [x] request location change to: {lat, lon} (ask the user if he / she wants to teleport or navigate. 'To' is optional. If it is not set, show the coordinate selection and return the result to applescript ?)
• [ ] zoom direction: enum (in, out)
• [x] move direction: enum (up, down, left, right)
