iCrew: Lifeboat Availability

A big update, much of it from crews' feedback. NEW - Calendar: book time off for a day or a run of days, with start and end times if you need them, and tap anything under "Coming up" to cancel it or change it - Set my rota: set your pattern once and the app follows it - with shift hours, so night and day shifts only book you off while you're at work - A new Edit availability screen: your day in colour, tap or drag the hours, then pick a status - A new Team screen: your status as a coloured pill, solid status icons, unavailable crew dimmed - Dark mode across the whole app (Settings > Appearance: Light, Dark or Automatic), and your station can set the default - Settings > Crew list: sort by rank, availability or name, show ranks, and choose which view the list opens on - Your next planned change is shown under your status - The Overview shows how many are available each hour - Answer a call-out straight from the notification: responding, delayed or not responding - Auto book-off: say how long you're available for and the app books you off on time - Quiet alerts when you're booked off (optional) - Your station's own logo in the app - "Re-register this device" if alerts ever stop arriving IMPROVED - Picking your current status again clears an old "until" time - One set of status icons everywhere - Faster, clearer status picker and booking screens - Lots of smaller fixes and tidying
