Due to the implementation of the approve() function in LPTokenMaster.sol  its possible for a user to over spend their allowance in certain situations. See unboxing erc20 approve issues.
Recommend that, instead of having a direct setter for allowances, decreaseAllowance and increaseAllowance functions should be exposed which decreases and increases allowances for a recipient respectively.
