Extend tm script to allow session file loading

With the `tm script.conf session-name` format, or `tm script.conf`
format, it now allows setting up pre-defined session setups to be loaded
by tmux.

cat <<-EOF
Usage: $0 [FILE] [NAME]
Attach to an existing tmux session, or bootstrap a new session.
If no session exists which fits the criteria, this will create a new one and
load it up obeying the commands contained in the FILE argument passed in. It
must contain commands which are tmux-command compatible since they will be
passed to tmux unmodified.
It will load the default tmux.conf in the following order:
- XDG_CONFIG_HOME/tmux/tmux.conf (usually ~/.config/tmux/tmux.conf)
- ~/.tmux.conf
- /etc/tmux.conf
Afterwards, it will apply the contents of the FILE argument passed into the command.
If no FILE argument is passed it will create an empty session, or attach itself to
the session specified.
If no NAME argument is passed it will automatically create a session name from the
FILE argument passed.
