Subject: [PATCH] Change booleans to uints

"Under the hood of solidity, Booleans (bool) are uint8 which means they use 8 bits of storage. A Boolean can only have two values: True or False. This means that you can store a boolean in only a single bit." So I adjusted "unlocked" to uint256 to save some gas :)
