powerline-config tmux setup fails when using tmux compiled from github master since tmux commit c034670

[agrajag9]

In commit c034670 to the tmux repo, powerline-config tmux setup has returned the following error:

Traceback (most recent call last):
  File "/usr/local/bin/powerline-config", line 22, in <module>
    args.function(pl, args)
  File "/usr/local/lib/python2.7/dist-packages/powerline/commands/config.py", line 15, in __call__
    self.function(*args, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/powerline/bindings/config.py", line 181, in tmux_setup
    tmux_version = get_tmux_version(pl)
  File "/usr/local/lib/python2.7/dist-packages/powerline/bindings/tmux/__init__.py", line 79, in get_tmux_version
    major, minor = version_string.split('.')
ValueError: need more than 1 value to unpack

This is due to tmux author @nicm removing the version number from configure.ac so that tmux -V now returns tmux master instead of tmux 2.4.

programs should not rely on the format of tmux -V
