Subject: [PATCH] Bug 534944 - Avoid loading/importing weave files until
 necessary to speed up fennec startup Have importing service.js trigger
 startup instead of only starting up from Weave.js, which now is used as a
 backup kickstarter. Only call import(service.js) when necessary from various
 Fennec files.
