npgsql - Npgsql2: [#1010216] Array Handling.

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

[#1010216] Array Handling. Not fully tested by comments welcome
Added support for array datatype. Anything that implements IEnumerable<T> where T is a type already supported by npgsql will be treated the same as T[], anything that implements IEnumerable<U> where U implements IEnumerable<T> will be treated the same as T[,] (but cause an error if it's a "jagged" array, as postgres doesn't support them) and so on. In order to use it, just use an array or IEnumerable<T> as parameter value. Also, you can specify the NpgsqlDbType as an or'ed value to say it is an array: Binary or with other values. E.g. Array of Box is NpgsqlDbType.Array | NpgsqlDbType.Box. Thanks Jon Hanna (jon at hackcraft dot net) for patches. Also thanks Michael Parshin (parshim at gmail dot com) for his help fixing bugs.
