Bug Fixes

• Fix startTimestamp for burned tokens being larger than their correct values.
  Casting uint256 to address in Solidity does not necessarily set the upper 96 bits of the word to zero,
  causing dirty old bits to overlap with the newer bits.
  Addresses are now explicitly masked to clear the upper 96 bits when packed into a uint256.
