    syncthing.sh: Syncthing + tmux control

This is a simple script to control syncthing. It is
possible to also source this script in 'sh'-like shells (tested in dash,
bash and zsh).
When used as a script it accepts a number of subcommands; if sourced, a number
of syncthing_* functions are defined.
Functions / subcommands

syncthing_start / syncthing.sh start

Starts the Syncthing process silently into a background tmux session.
syncthing_open / syncthing.sh open

Open a browser window with the Syncthing web GUI; if a session has not been
started beforehand, it is started before the web GUI is launched.
syncthing_stop / syncthing.sh stop

Stops the Syncthing process and the tmux session.
syncthing_inspect_tmux / syncthing.sh inspect_tmux

Opens the tmux session for inspecting the log, if necessary.
syncthing_session_started / syncthing.sh session_started

Exits with exit code 0 if a tmux session with Syncthing has been started;
exit code 1 otherwise. (The output is always empty)
