Log server activity, scrollable chat tabs, and move info panel to a chat tab

Native TS3 logs client joins/leaves/moves, group changes and channel edits
to the server tab; minor local-only notices (mic mute, tray) no longer
spam the log. Chat tabs scroll by mouse wheel like server tabs. The info
panel can now be moved into a persistent, generically-labelled chat tab
that tracks tree selection and collapses the panel's space entirely; a
tree rebuild no longer briefly fires a null selection that reset this.
Added "Find Client in Channel Tree" to the client context menu, and tree
selection now survives model rebuilds.
