Convert webkit_glue.cc over to using WebKit API.
Convert webkit_glue.cc over to using WebKit API.

Removed unnecessary code to reset the JS line number, which was
only added for the Chrome+JSC build.  I don't have a way to test
if it would still be necessary, and I'd rather not add a WebKit
API for it unless I can prove that I need it.
