Can I generate model with pointer fields? gf gen dao

[cindoralla]

Description

Thanks for the great work! When using "gf gen dao", the fields of mysql are not null, could you please add a config to make them as pointers? Because our system contains lots of nullable fields and existed logics using the nullable. So I cannot directly make them as not-null.

And now I manually edit the entity dao files to mark the fields as pointers, but it's a good idea.

need to add new config field ?

	localTypeNameStr = string(localTypeName)
	nullToPtr := true // need new config field to enabled null to pointer.

		localTypeNameStr = "*" + localTypeNameStr

Thanks! Let me have a try.
