Optionally set a separate Javascript server and path

We have about 10-12 JavaScript pages per Web page. They usually
are based on the same server as the Web pages, but since they're
static files, it makes sense to offload them to a lite server that
handles static files well.

This commit lets you set a separate Javascript server and path for the
default Javascript code in StatusNet.
