YGDL [YGGDRASIL] Token

YGGDRASIL.addLiquidity(uint256,uint256) (#2337-2350) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,DevWallet,block.timestamp) (#2342-2349)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Contract YGGDRASILDividendTracker (#2367-2626) has payable functions:
- DividendPayingToken.receive() (#1429)
- DividendPayingToken.distributeDividends() (#1444-1457)
