npgsql - Npgsql2: Added method AddWithValue and made Add(String,

Log Message:
-----------

Added method AddWithValue and made Add(String, object) obsolete and this was causing ambiguity problems with Add and NpgsqlDbType and DbType. See http://pgfoundry.org/tracker/index.php?func=detail&aid=1010714&group_id=1000140&atid=590 and http://pgfoundry.org/tracker/index.php?func=detail&aid=1010715&group_id=1000140&atid=592 for more details. Thanks Gildas (prime.gildas @nospam@ gmail.com) for heads up and discussion about that. Note that the issue of adding a new method which takes a DbType parameter is not finished yet. We should check if this is still needed.
