Use preferences manager (starting Sprint 36).
Change Brackets version (dep on prefs)
Use "session" scope instead of creating new one

Fix the late night copy/paste mess too...
Bump the version to 0.0.4
Fix #3, #6 (partially).

Fixed major screw up with preference management.

Missing things for #6: defaults are read only once. Should be re-read
each time project changes.
Always use fallback instead of user defaults.

May slow down the extension a little bit. To be figured out...
Add overall timer.
Merge branch 'sprint-36'
