hgweb: use a function expression for the install listener of followlines UI

We define the listener of document's "DOMContentLoaded" inline in registration
and use a function expression (anonymous) with everything inside. This makes
it clearer that this file is not a library of JavaScript functions but rather
an executable script.

(Most of changes consists of reindenting the "followlinesBox" function, so
mostly white space changes.)
