Prevent bar being stopped by using signal other than SIGSTOP #701

  1. Prevent bar being stopped by using signal other than SIGSTOP 

    i3 sends SIGSTOP to the bar when it is hidden, which causes the bar to stop
updating. This is done for "power savings" and is not configurable in i3 at
the moment, which inconveniences users of blocks in i3status-rs that are
meant to be running at all times.

Luckily i3 lets us customise the signal it sends, so we can set it to something
other than SIGSTOP to effectively allow non-interrupted of the bar in all
situations.

Fixes greshake#503, greshake#694 and possibly others.

  1. Use SIGCONT instead of SIGUSR2 

    Since SIGUSR2's default action is to kill the process if there's no handler registered.
