semantic improvements: determineReward / claimReward / tokenClaims

[kangarang]

1. determineReward: gets the number of tokens for the winning party of a challenge (Applicant or Challenger, not Voter)

How about challengeWinnerReward? (same implementation as the now deprecated #10)

---

2. claimReward: only deals with Voter.

How about claimVoterReward? (same implementation as the now deprecated #10)

---

3. tokenClaims: sounds like it would return true if a voter has claim to some tokens. however the opposite is true. (clearly i was confused in Semantic improvements #9)

How about voterClaimedReward?

The variable reward can be renamed to be more specific to the challenge winner:

tcr/contracts/Registry.sol

Line 383 in 57021d4

uint reward = determineReward(challengeID);

The variable reward can be renamed to be more specific to the voter reward pool:

This comment could be improved to be more specific to the total number of tokens that will be rewarded to the majority bloc of voters:
