Mailcal 1.0.0 beta

First beta of Mailcal, a mailbox.org calendar for the Light Phone III.

• Agenda from today (30 days back, a year ahead) with start and end times
• Add, edit and delete events; repeating events ask "this one" or "all"
• Show or hide calendars, pick where new events go
• Talks to mailbox.org directly over CalDAV; no DAVx5, no phone calendar
• Offline copy for reading; changes need a connection
• Internet permission only

Install: adb install -r mailcal-1.0.0-beta.apk. Sign in with your mailbox.org email and password (an app password if you use two-factor sign-in).
