ARC [ARCADE] Token

Arcade.addLiquidity(uint256,uint256) (contracts/Arcade.sol#670-683) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (contracts/Arcade.sol#675-682)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Arcade.updateMaxSellTransactionAmount(uint256) (contracts/Arcade.sol#314-324) contains a tautology or contradiction:
- require(bool,string)(maxSellTransactionAmount >= 0,Arcade: invalid maximum transaction amount) (contracts/Arcade.sol#318-321)
Fix the incorrect comparison by changing the value type or the comparison.
