feat: autohide improvements

- Adds new setting "Enable inactivity hide during battle" (default:
  true) which determines whether autohide should apply during battle
  (thanks @aurieh)
- Adds new setting "Chat channels considered for activity" which allows
  customizing which channels incoming messages must match to "bump" the
  inactivity timer
- Adds new per-tab setting "Unhide the chat window on activity" to
  configure whether it will be considered for "bumping" the inactivity
  timer when receiving messages that match the new channel filter. Note
  that the foreground tab is currently always considered.
- Extends autohide code to apply to poped-out tabs as well. Each popout
  window has its own inactivity timer, but focusing the main window will
  restore all popped out windows.
