add restriction for checking what alternative cost was paid. combined with if/ifnot ability becomes a very powerful tool.

paid(blah)
auto=if paid(alternative) then damage:3 target(creature)
auto=if paid(alternative) then life:10 target(player)
auto=ifnot paid(alternative) then damage:3 controller
auto=ifnot paid(alternative) then life:4 opponent

it can be used any place a restriction can be used. 
rearranged the constants for the payment type keywords to match the order we int the alternatePayment array on a card, added keywords for the remaining payment types, 

    "notpaid",
    "paidmana",
the 2 above pretain to paying the real manacost of a card
it checks the mana={1} cost line and is not joined to the other types.

    "kicker", 
    "alternative", 
    "buyback", 
    "flashback", 
    "retrace", 
    "facedown",
    "suspended"

note: all test pass in this revision.
