- new features by Zethfox:
-- "oneshot" optional parameters for lords (helps fixing issues with bouncelands)
-- Life as a cost (avoids using a dirty trick of paying life as an effect)
-- set life total abilitiy (lifeset
-- new auto lines: autostack, autoexile

The test suite passes with these changes, also no test using these abilities has been added yet
