Patch providing CEF3 GetSource(), GetText() and general StringVisitor support

[GoogleCodeExporter]

The attached patch adds support to CEF3 cefpython for the GetSource() and 
GetText() methods. These methods are asynchronous in CEF3 unlike in CEF1.

StringVisitor C++/Python classes are added and used to call into a Visit() 
method to cef to be asynchronously called when it has the page source or text 
ready to be returned.

This is used to pass the returned source or text into a user's python program.

wxpthon.py and wxpython.html have been modified to demonstrate both methods 
with javascript calls to dump page source or page text to console.

Patch looks good, thanks Greg. Some comments below.

StoreUserStringVisitor, GetPyStringVisitor, PyStringVisitor and 
makeStringVisitor should go to the string_visitor_cef3.pyx file.

In the wxpython example there should be a comment about keeping a strong 
reference to the StringVisitor object during the visit.

I will make these changes when patching.
