Fix getAdapterConnection() to not always create a new connection

$adapterConnections is a class property not a local variable here
Removed all peer stuff.

Adjusted documentation, .xml etc.
Abstracted connection handling, so we don't deal with PDOStatement directly anymore, but with DataFetcher, which hides the adapter specific stuff. (PDOStatement etc.)
