Allow tmux session name to be passed as env var

For normal usage this change should be a NOOP. However it enables the
use case where the user might want to predefine what session gets
connected to when the shell is launched. Running `zsh` will still net
you a connection to the last used tmux session or a new one named
"zprezto" if none exists. However `env tmux_session=myname zsh` will
connect you specifically to a session called 'myname' including creating
it if it doesn't exist.

This is particularly useful in window managers where a key binding might
open a terminal with a predefined session or even show a list of current
sessions and open a new terminal connected to that session.

The default session name may still be set using zstyle as documented.

Tmux

Defines tmux aliases and provides for auto launching it at start-up.

Settings

Auto-Start

Starts a tmux session automatically when Zsh is launched.

To enable this feature when launching Zsh in a local terminal, add the following line to zpreztorc:

zstyle ':prezto:module:tmux:auto-start' local 'yes'

To enable this feature when launching Zsh in a SSH connection, add the following line to zpreztorc:

zstyle ':prezto:module:tmux:auto-start' remote 'yes'

In both cases, it will create a background session named prezto if the tmux server is not started.

You can change the default session name with:

zstyle ':prezto:module:tmux:session' name '<YOUR DEFAULT SESSION NAME>'

A session name may also be specified in an environment variable before ZSH runs.

env tmux_session='<SESSION NAME>' zsh

This can be useful for example to connect to a specific remote session connecting via SSH (note that OpenSSH needs to be configured to pass on that environment variable). It can also be used with window managers to set keybindings that launch terminals with specific sessions.

With auto-start enabled, you may want to control how multiple sessions are managed. The destroy-unattached option of tmux controls if the unattached sessions must be kept alive, making sessions available for later use, configured in tmux.conf:

set-option -g destroy-unattached [on | off]

iTerm2 Integration

iTerm2 offers significant integration with tmux. This can be enabled by adding the following line to zpreztorc:

zstyle ':prezto:module:tmux:iterm' integrate 'yes'

Read iTerm2 and tmux Integration for more information.

Aliases

tmuxa attaches or switches to a tmux session.
tmuxl lists sessions managed by the tmux server.

Caveats

On macOS, launching tmux can cause the error launch_msg(...): Socket is not connected to be displayed, which can be fixed by installing reattach-to-user-namespace, available in Homebrew, and adding the following to tmux.conf:

set-option -g default-command "reattach-to-user-namespace -l $SHELL -l"

Furthermore, tmux is known to cause kernel panics on macOS. A discussion about this and Prezto has already been opened.
