Subject: [PATCH] home: tmux: add 'enabledPassthrough'

This is useful for cases where some programs expect to be able to use
the tmux passthrough escape sequences by using the tmux passthrough
sequence.

One such example is `osc52` script I packaged.

However I like the idea of tmux filtering all escape sequences by
default, so it's not enabled by default.
