Greasemonkey: add a way to register scripts directly.

Previously to add a greasemonkey script you had to write it to the
greasemonkey data directory and call load_scripts(). Now you can just
make a new GreasemonkeyScript and pass it to add_script(), yay.

There are no users of the method yet although I could have used it while
writing the tests.
