Create a speeches base template for clean install.

Adding this base file means it does not have to depend upon the parent
project having a base template already in existence, and it is easy for
a project to override to use its own base template instead.
Move static files to temporarily appropriate places.

jQuery is needed by the app, so move it in there.
Reinstate the bits of the old speeches.css that are still used,
inside the speeches.scss file.
