Various gas saving measures for the claim function

[waynehoover]

Some small refactoring that save about 3k gas.

• reduce gas by

  • not doing the same checks in the factory as in the singleClaim function on each quest contract
  • removing the NFT fee from NFT quests as this is not used

• [ ] remove numberMinted from questFactory and use redeemedTokens on quest instead.

• renames some errors to be consistent on each quest contract
