Ensure constant javascript_enabled for HTML contents.

Now we take the value of the javascript_enabled option when the
content is created.  We then use the content's script_enabled
boolean everywhere else.

This prevents us getting inconsistent values for javascript_enabled
if a user toggles the setting while a page is loading.

It was read frequently during box construction, and also the
parser's script enabled setting could change where we handled
a change of encoding.

Now we only care about the setting of the javascript_enabled
option at time of html_content creation.
