Start of restructuring to allow overlays include subset of providers

This allows us to build a UnifiedEmail that supports all providers
and use this base to build applications that only supports a subset
of the providers

Made AccountCacheProvider and ConversationProvider abstract.  This allows
the extending class to specify the authority that should be used (This allows
both UnifiedEmail and Gmail to be installed at the same time)
