[webkit-gtk] Webkit introspection experiments with Python

I modified the script like Martin suggested and its working fine right now. One 
more problem remains, the introspection scanner uses the class naming 
conventions to determine if certain method belongs to a class, for example...

For the WebKitWebView method webkit_web_view_get_dom_document it removes the 
prefix WebKit and splits the class name in capital letters separating them by 
underscores, and then it matches this to the method names, so it can tell that 
this method belong to the class.
But, for example for WebKitDOMHTMLElement method 
webkit_dom_html_element_get_inner_html this doesnt work, because the scanner 
tool processes WebKitDOMHTMLElement as domhtml_element instead of 
I thought of using the Rename to: parameter in the comments to account for 
this difference (renaming for introspection purpouses 
webkit_dom_html_element_get_inner_html to 
webkit_domhtml_element_get_inner_html), but this doesnt seem to work. I also 
thought of fixing the class names generated so they follow the convention 
WebKitDomHtmlElement for example, but this (as expected) brings problem in a 
lot of places. The same goes if instead of renaming using a introspection 
annotation I actually rename functions.

So, the question here is what's the best approach to solve this. It seems that 
the "rename to" annotation is the path of least resistance, but it doesnt 
quite work and in the end it's a workaround. Another alternative would be to 
talk to the introspection tool guys about improving the detection routine.

The consequence of this is that in a language like Python, the "self" variable 
isnt automatically passed to the functions, and you have to pass it manually 
as the first parameter of the function. Its not the end of the world for sure!
