WhatsApp Access 0.2.0

Almost everything WhatsApp Web does, now in the add-on.

• New sections: Starred (Ctrl+5), Channels (Ctrl+6), Communities (Ctrl+7) and
  Settings (Ctrl+8).
• Channels: read posts, react, follow and unfollow, and find new channels.
• Communities: their groups and announcements; join a group or ask to.
• Settings: your profile (name, About, photo), privacy settings and blocked contacts.
• Status: write a text status, post a photo or video, and see who saw your statuses.
• Messages: create polls, pin and unpin, reply privately in groups, see who reacted, send contact
  cards and stickers, and answer or create events.
• Search the messages of every chat (Ctrl+Shift+F); a chat's media, links and documents; pinned
  messages; unread mentions in groups (Ctrl+Shift+M).
• Groups: create one (Ctrl+Shift+N); for admins, name, description, settings, invite link and
  members. Exit a group, block, report, clear or delete a chat, disappearing messages, favorites.
• Group voice calls: start one, or join the one going on; groups with a call say so in the chat list
  and at the top of Calls, where Enter joins. Joining a call you are invited to again answers it.
• In a group call: the participants, who is muted or raised a hand; raise your hand (Ctrl+H), send
  reactions, ask someone to mute, and hear who is speaking (Ctrl+Shift+G). Joins, leaves, raised
  hands and reactions are said with small sounds.
• During a call: NVDA+Alt+M mutes or unmutes from any program, with a sound for each; the WhatsApp
  window shows Return to call and Mute microphone; NVDA says when someone else mutes you.
• Last seen, online, typing and recording now arrive: you are online while the WhatsApp window is in
  front, and offline when you switch away or close it, as with WhatsApp Web.
• Chats with disappearing messages say so, with how long.
• People not in your contacts are named by their contact or phone number, not a long number.
• NVDA says when WhatsApp loses its connection and when it is back.
• Notices and other special messages are read in WhatsApp's words; view-once media says to open it
  on the phone.

Fixed:

• Labels in the new dialogs were read for the wrong boxes.
• When a dialog or a question from NVDA was open, coming back to WhatsApp said "unavailable"; it now
  goes to the open question.
• Menus and call buttons no longer have clashing or extra Alt keys.
• The Open chat button is gone (Enter opens a chat); the Sections list opens with Enter.
