Refactoring Model::exists() to be independent of Model::$useTable. Fixes #199.

Browse source 
Model::exists() now makes no check whatsoever on the value of
Model::$useTable. This means that, as with a database-backed dbo,
Model::exists() will call Model::find('count') (which in turn calls
DataSource::read()) to determine if the record identified by Model::$id
already exists in the datasource.
