Add screen output pipe command option

Browse source 
Allows piping all pane saving through some command. Default is cat,
effectively a noop.

One example use case (how I plan to use this) is to pipe all output
through `ts`, prepending timestamps to captured output.

set via
```
set -g @screen-capture-pipe-command 'ts'
```
