enhancement: add all events needed to allow a subgraph to rely on event handlers only

[LufyCZ]

For example, this event should also fire somewhere in the initMarket function, as the time is set there as well.

We should also consider adding completely new events for, among others, the initMarket function, as it is currently not possible to track things like token or paymentCurrency on the subgraph without resorting to call handlers

Proposing these:

• AuctionDeployed(address funder, address admin, address wallet, address token, uint256 totalTokens, address paymentCurrency, address pointList
• AuctionFinalized() => AuctionFinalized(bool successful)
• PointListUpdated(address pointList, bool enabled)
• TokensWithdrawn(address token, address to, address amount)

Might add more if I think of any
