Laser Slicer v0.8

I just put a very long overdue update to the Laser Slicer script in the 'Scripts' section. Changes in this update include:

• Laser Slicer now sits in the 'Laser' tab for recent Blender versions. 
• New options can place each slice in a separate file with the following positions:
• Top left - slices are in the top left of each sheet
• Staggered - slices are positioned on each sheet as if they were positioned on one sheet.
• Centre - each slice appears at the centre of each sheet.
• A cut thickness option to specify a gap between slices.
• The number of slices that will be cut are now estimated so you can see if you have a long wait in front of you.

This is an initial version so bug reports are welcome and probably inevitable.
