[Squeakland] Copy an object programmatically.

The key is that you can create a variable which is of type 'Player' (on the
variable's menu, select 'change value type' and choose 'Player').  E.g., I
created a player variable called 'clone1' for my sketch (actually I called
it 'clone', but apparently it conflicted with some reserved var, so a '1'
was appended).  You can then 
1) assign something to that var - e.g. 'sketch's copy', and
2) use that var on the left-hand of an assignment - e.g. replace the
'sketch' in 'sketch's x <- <value>' with 'sketch's clone'

Hopefully the attached image will help clarify.

You might also want to get in the habit of doing things in a playfield
instead of in the world.

Please copy the list if you still have problems.
