Print button

This allows to print the graph view of the state or the history:

It seems there's no way to print the scaled svg chart, it will be cropped as we don't know the final size, so I'm resizing it back while printing (as seen in the demo above).

@jhen0409, seems like Electron cannot print from devpanel. Even though window.print() shows the system's print preview dialog, it has no effect. In Chrome it also doesn't work as expected when it's from devpanel (hangs the browser under some circumstances). So, I didn't include this button on devpanel, only when opening the extension's window.

On the other side, when calling window.print() from Electron's window it works as expected So, you can use it in react-native-debugger without problems, just make sure to adapt the css as in https://github.com/zalmoxisus/remotedev-app/blob/master/src/views/index.jade#L28-L48.

It's up in remotedev-app@0.8.0-beta-10.
