Ian Gilman 9a28d8cd19 + Lots of cleanup after the sessionstore transplant
+ Now saving pageBounds.
+ Removed some unnecessary save calls and added some necessary ones
+ Added a reset command to the dev menu; wipes storage and refreshes
+ Fixed the save command on the dev menu so it now works again
+ Reconnected storage sanity checks
+ Removed a bunch of now unused storage code
+ Fixed a problem with cold start
+ Removed a bunch of logging code
+ Pulled BrowserWatcher out of tabs.js
+ Added a direct link to the code documentation to the dev menu
