temporarily disable alpheios for performance in ff

Temporarily turn off Alpheios Tools due to performance issues in
Firefox. When enabled, it causes the browser to lock up for 200-500ms
for some reason.

Possibly re-enable it with a later version of configure it to activate
when a user clicks a button (see
alpheios-project/embed-lib#118 (comment))
