Implement options_after window option

[sebastianst]

Created new method config_after_window() that applies relevant configurations after windows and panes have been created.

Currently, it only knows the options_after option. This is useful for setting synchronize-panes: on after pane creation and shell command execution.

The same could be done for panes, but I don't know of an application for that at the moment.

sh of Travis CI interpretes the Up key sent by libtmux as ^[[A instead of repeating the last command... It worked on my machine. What would be the best way to test the last input command in Travis CI, if not in /bin/sh with cmd('send-keys', 'Up')?

[sebastianst]

It was quite some effort to get the tests working on Travis. Because of slow execution of the echo commands, I had to use the trick from test_suppress_history with a sleep(.1) loop to make them work. Also, tmux 1.8 has a bug apparently by which capture-pane has trailing empty lines...
Now the tests go through. The included commits were actually squashed from 9 commits until I got it working on my CI testing branch.

@sebastianst Looks good. Can you add an example to the documentation?

• https://github.com/tony/tmuxp/blob/master/doc/examples.rst (https://tmuxp.git-pull.com/en/latest/examples.html)
• https://github.com/tony/tmuxp/tree/master/examples

[sebastianst]

Sure, will do next week!

[sebastianst]

Done. The example shows how to ssh into two different servers with synchronized
panes.

[tony]

Nice job @sebastianst!

[tony]

This is now live in 1.3.0

[sebastianst]

Great, thank you!

[sebastianst]

One question on the release though: The github latest release is still set to 1.2.1 - is that intentional?

[tony]

Nope, it's about 8 or so releases behind.

I just don't update releases, the main ways of grabbing it are pypi, git (via master or the tag) or a package manager.

That said, I went ahead and issued a 1.3.0 released.

Also, in c7b2cc7, I had to fix the link to this issue in CHANGES. That should be live on the docs in a few minutes. You may have to hard refresh.
