Break actions when they need too many conditions

[MikeTaylor]

At present, if an action or occurrence has too many instructions associated with it, the ScottKit compiler will automatically break it into a sequence of actions, all but the last finishing with an inserted continue.

We also need to do something analogous when we have an action or occurrence with too many conditions. If we use something like

action TO RAIL when carried rope and flag 3 and at balcony
	clear_flag 3
	destroy rope
	drop ropetied
	print "OK."
	look

saying:

scottkit/lib/scottkit/compile.rb:463:in `block in generate_code': condition has 6 conditions (RuntimeError)

But you can work around that by inserting continue occur 0% between the second and third actions.

The compiler should do this for you.

This workaround isn't effective for me.

This code:

action give script when here players and flag 5 and carried script
	print "We can play the MURDER OF GONZAGO!"
	print "They exit to the throne room"
	print "The play is ABOUT to begin!"
	destroy script
	put players throneroom
	continue occur 0%
	put claudius throneroom
	put gertrude throneroom

only puts the players in the throneroom, it doesn't move claudius or gertrude.

With the continue commented out, I get

jcompton$ scottkit -p rotten/rotten.sck

Another possible clue?

Replacing continue occur 0% with set_counter 1 produces the same behavior: the game compiles but the full list of actions doesn't take place.

(in any event, more informative error messages would also be appreciated here. It's not always clear at all where the problematic condition is!)
