Loading error fix (possible) and button fix

I believe this fixes the problem. Before I was able to repro the
problem by reloading the page by pressing enter on the url bar.
That no longer seems to be reproducing the problem.
So, I believe the problem was that the script for the callback was not after
all of the include (srcs).
In the process of this I found a way to get rid of the hashtag in the url
and added sage's favicon.
