Add bindings for SetZoomLevel in WPF

[salmenf]

It'd be nice if someone could add these bindings and include them in the next release. What I mean:
The C++ CEF API exposes the method SetZoomLevel in the CEFBrowser class. Most other methods listed there already have bindings, but for my project, SetZoomLevel would be very useful.

Hi,

It has been experimented with before, see this forum thread: https://groups.google.com/forum/#!searchin/cefsharp/zoom/cefsharp/0o7fOJy-ijw/GMVGb4ED7PMJ

Unfortunately, there hasn't been any more formal PR done though. For me, this is not a critical issue so it's not likely that I will personally spend much time on it, but if you like & have the time and energy, feel very free to fix it and submit a pull request.

@perlun What is the correct tick value for the zoom slider? I could not find a good value by looking at the upstream documentation.

@Freddex

// set zoom level
WebView.ZoomLevel = 0.3;

// reset zoom level
WebView.ZoomLevel = 0;

@peters: thanks, will review the PR ASAP. As for the tick value, this is what the C++ cefclient has, so I guess we can use something similar:

  case ID_TESTS_ZOOM_IN:
    if (browser.get())
      ModifyZoom(browser, 0.5);
    return 0;
  case ID_TESTS_ZOOM_OUT:
    if (browser.get())
      ModifyZoom(browser, -0.5);
    return 0;

Thanks a lot for taking care of this, works fine now.

Reopening this since it's not yet fixed for CefSharp3.

Since #306 is merged now I think we can close this
