REDFEG 🦍 [RedFeg] Token

RedFeg.sendETHToFee(uint256) (#430-433) sends eth to arbitrary user
Dangerous calls:
- _FeeAddress.transfer(amount.div(2)) (#431)
- _marketingWalletAddress.transfer(amount.div(2)) (#432)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract ticker (REDFEG 🦍) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Ownable._previousOwner (#151) is never used in RedFeg (#214-613)
