Title: Impossible to bind a null value

Fixes issue where it is impossible to bind a null value. For instance $table->bind( array( 'someid'=>null ) ); As isset determines if a variable is set and is not NULL. NULL values are needed where the INNODB foreign key is not set yet or needs to be cleared.
