Work in progress on getting bootstrapping working.  Not functional, but a lot of things converted to load dynamically.
Mostly working bootstrapped version.  Some of the Firefox only code (code that doesn't run in Zotero Standalone) is not firing yet.  Need to debug memory clean up on addon diabling.
Working bootstrapped version of Zutilo.  Needs a little more testing.
Small bug fix in updating Zutilo version preference
Remove initialization delay.  It was causing errors when the addon was quickly disabled/enabled because the bootstrap.js shutdown() function was being called during the delay before the initialization function was called.
