Implement temporary First Run Dialog on OS X

We use a modal dialog with a single checkbox on OS X.

We use the OSX defaults system since we want something quick and reliable.  The
dialog is displayed at a very early stage in Chrome startup (Before any
subsystems start relying on the stats variable).  This means there are a few
quirks in displaying the UI.

A change was also needed to our event handling code since when the dialog is
shown we spin an event loop at a very early stage in the process lifetime.

Changed default value for stats to false and updated unit tests to reflect that.

Also some misc. minor cleanup.
