Admin and Operator management contract

[calvinmd]

BitGuildAccessAdmin.sol

• Based on Ownable
• Operators can add or remove other operators
• Only the owner can transfer ownership, remove all operators, reset MAX_OPS
• Modifiers: onlyOwner, onlyOperator (owner has all ops rights. implied)
• Public variable/functions: operators (address []), owner, MAX, opsCount()
• Public functions onlyOwner: transferOwnership(_newOwner), removeAllOps(), updateMax()
• Public functions onlyOwnerOrOperator: addOperator(address), removeOperator(address), getAllOps()

BitGuildWhitelist.sol

• Based on the Crowdsale whitelist contract
• Added add and remove whitelist functions
• Updated the old bulk update to work with arrays
• Added getter for count and entire whitelist
• Didn't add remove all since we may not want to have zero game contracts

All functions are tested on Rinkeby and worked as expected.
