Summary: Fix Sprite memory Leaks

Details:
LzMakeLoadSprite.*, LzSprite.*: Eliminate recursion argument. Not
used for sprites.
LzSprite.*: In #destroy set __LZdeleted flag to prevent events
from resurrecting you. No need for recursive sprite destruction
now. Move delegate removal back to destroy from predestroy.
LzIdle: Be careful to create coi Array on instance, not prototype.
LzNode: Comment and simplify $once and $always processing. Add
comment to explain importance of __LzDeleted flag.
LaszloView: Destroy the sprite _before_ you check for a recursive
call.
LzReplicationManager: Remove superfluous call to LzSprite#destroy.
newcontent, scrollingtext: Remove unused id (that causes a leak).
Tests:
I modified Phil's test case to only create/destroy 1 window per
click. The test methodology is:
1. Start test
2. Click twice to create any shared substrate
3. Debug.markObjects()
4. Click once
5. Debug.findNewObjects()
6. Debug.whyAlive()
Result: Before change, many leaked window sprites. After change, no
leaked window sprites.
NOTE: There are still some other minor leaks that I have not
attempted to address here, but will report as a separate bug.
