Fixed a mistake in the code (wasn't supposed to princ)
Fixed a bug and added LayerFreeze.lsp

Bug for SuperQuickSave: if the [DWGNAME]-temp layer state was current
layer then the layer wouldn't be selected after the save and everything
would be frozen after function completion.

Changes for SuperQuickSave: Added a completion message when function
finishes (and removed the return value being "nill")
