Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

Contract locking ether found:
Contract MainToken (#737-854) has payable functions:
- MainToken.fallback() (#850-852)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.

SafeMath.nthRoot(uint256,uint256,uint256,uint256).x (#200) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

MainToken.unlockToken() (#841-848) uses timestamp for comparisons
Dangerous comparisons:
