Title: Add -U (--upgrade) to upgrade a theme with pelican-theme

I disliked having to do:

$ pelican-theme -r -i

So I modified install() to handle an upgrade of an existing theme. While doing
so, I noticed that in install() and symlink() the script would error with 'no a
directory' instead of 'not a directory'. So I fixed that for you as well.
