Do not set IDataParameter.DbType when creating input parameters #159

See this StackOverflow question:

It seems to me that the DynamicParameters.AddParameters method shouldn't 
explicitly set the DbType or size for input parameters, unless explicitly 
requested by the caller.

I.e. the following line should be removed:

    if (dbType == null && val != null) dbType = SqlMapper.LookupDbType(val.GetType(),name);

When writing ADO.NET code by hand, one doesn't generally explicitly set the 
DbType.
