Preparing PS2 Port

Bug Fixed - vertical placement of rush.

ReOrganized menu system layout.

Remove layer property in entity since it is never used.
Display fps with ram used under the screen.

Give spawn entry a model property, reserved for direct spawn via model.

Also replace defaultname in entity with defaultmodel, because a model handle must contains a name, and it is faster to spawn with a model handle without searching through the list.
