Heal Block Fixes

Aqua Ring:
-Blocked when Heal Block is up
-Displays message before healing. Looks much smoother when multiple effects are in play (Leftovers, Ingrain, Aqua Ring, Leech Seed, and Giga Drain when I was testing). In addition, Leftovers is set up to send message THEN recover. No need for inconsistencies.

Leech Seed:
-Prevented healing when Heal Block is in effect
-Order of message (same as Aqua Ring) 

Ingrain:
-Blocked when Heal Block is in effect
-Removed message saying that Ingrain healed despite it not actually healing at that point
-Order of message (same as Aqua Ring)

Substitute:
-Random space change I didn't touch
