[svn] Ancestral Life exploit

[lukep]

1. Get Ancestral Life up to a large portion of a turn recovered when gaining a regen effect (eg, 90%+, or over 100%)
2. Get some way of healing every turn, or more often (eg. Waters of Life, damage affinity, skullcleaver, bathe in light, Goedalath Stone + Healing Nexus, etc...)
3. After every heal, deactivate the regen effect generated by Fungal Growth. The turn that you heal on will not take any (or very little) time, but you will still be able to act normally on it.

This allows you to act at least twice as quickly as normal, or infinitely fast with Skullcleaver (and never missing) and >=100% of a turn recovered on regen.

This cannot be done in b40, because you can't gain regeneration effects more quickly than once every 5 or so turns.
