Keyboard problems in popup windows in the wxpython examples (Windows)

[GoogleCodeExporter]

There was a similar keys "chars" events problem when embedding browser
in wx tabs, this was fixed by adding the wx.WANTS_CHARS style to panel
and notebook controls. See this topic on the CEF Forum:

http://www.magpcss.org/ceforum/viewtopic.php?f=6&t=10922

Adding the wx.WANTS_CHARS style to wx.Frame does not solve the problem
for popup windows. This probably needs a more complex fix, requiring
to hook up to wx keyboard events and propagate them to the CEF child 
windows.

Setting style for wx.Frame:

    style=(wx.DEFAULT_FRAME_STYLE | wx.WANTS_CHARS)

I think that the solution is to create the popup windows explicitilly, by 
implenting the LifespanHandler.`OnBeforePopup` callback. Keyboard behaves 
correctly in the wxpython.py popup example when using the NewWindow() function.

Thanks, implenting the LifespanHandler.`OnBeforePopup` callback helped.
However this is not a straightforward solution as you can't create new window 
directly in this callback (as it is executed in wrong thread).

Issue 61 is to allow posting tasks on the UI thread.

Fixed in revision a07c898cb1df.

Exposed cefpython.`PostTask` function for execution of tasks on various 
threads. See example usage:

Note that are implications of creating the popup window of our own by 
implementing LifespanHandler.OnBeforePopup. The popup window and parent window 
will not be able to script each other. There will be no "window.opener" 
property available in the popup window.

The popup/parent scripting issues are to be fixed in a separate Issue 171.
