added ability to have triggered abilities target based on the event that triggered, bramblewood paragon, graft, etc.

use "trigger" inside target code of triggered ability.
does not work with @each and @next.
@damaged can use trigger[to] and trigger[from] to specify the target or source of the damage, respectively.

Adds cards:
Aether Flash
Bramblewood Paragon
In the Web of War
Juniper Order Ranger
Mortuary
Primal Forcemage
Fungus Sliver
Simic Initiate

as well as a test file for feral hydra, missing from my last commit.
and daily build.
