Use g_idle_add() to make the webkit_web_view_run_javascript() call run
on the GTK+ thread. Correspondingly, need to use a separate
short-lived thread to do the fakeSocketWrite() calls from
handle_lool_message(), so that the GTK+ main loop is ready to run the
added lambda. Or something like that.
Now it gets a bit further, doesn't crash, but just sudddenly exits
before showing the document even.
Add plumbing to send messages from the Online code to the JavaScript
code, and vice versa. Similar to what is done for iOS.
Sadly, it crashes. Multi-thread issues. Not surprisingly, it crashes
when I call webkit_web_view_run_javascript() in another thread than
the one where the GTK+ and other Webkit calls were done. I need to
come up with some clever way to do everything from the same thread.
(On iOS, I use dispatch_async(dispatch_get_main_queue(),...) to
schedule a block (i.e., a lambda expression) to be run in the main
thread.)
