v1.1.0beta2 - Group up!

• a nicer contacts view, grouped by the first letter
• push-to-talk
• call actions
  • set/change/clear password
  • rename call
  • share call
  • and many more options that I leave to you to explore!
• support for joining public calls (both WITH and WITHOUT the password)
• reworked call controls and audio-only call by default
• ability to create a group or a public call

And, of course, various other small fixes and improvements.
