Replicated a bug 'Dapper MultiMap doesn't work with splitOn with NULL
value' reported on SO http://stackoverflow.com/q/10744728/449906.
Dapper doesn't create an instance of the class if the first property
after split is mapped to a column with NULL value.

Updated Readme

Fixed a NullReferenceException when merging DynamicParameters

Add support for dictionaries/expandos to DynamicParameters + Refactoring

Add Npgsql nuget package

SQL Compact 4 support

Changed CreateTableConstructor to work for child table type

Throw an exception when asked to Delete<MyType>(null)

Throw an exception when asked to Delete<MyType>(null) rather than trying to as in Npgsql it will delete the whole table.

Added test for Posgresql Array parameters

Added test for insert updating object's key

Update object's key(s) after insert and array parameter support.

Added FeatureSupport Class to handle variations int DBMS features, used this to implement native array parameters for Postgresql.

Small but useful (I think) additions

Added postresql support for Insert to return primary key of inserted row.

Conflicts:
	Dapper.Contrib/SqlMapperExtensions.cs

Broke SqlBuilder to another assembly
Added Dapper.Rainbow (minimal ORM)
Changed nuget to distribute DLLs
