Reviewed by Ojan Vafai.

All functions relating to cross dashboard behavior move from being
globals to methods on the history.History object. Names stay the same,
except many are made private, ones that should have been constants now
are, and the long standing TODO to change "currentState" to
dashboardSpecificState is done.

We now create a global history object in dashboard_base, as an
intermediate measure.  Once the dashboard specific code is
added to history, each DB will need to create its own, and this
global will be eliminated.
