UNIC Token

UNIC.donateEthDust(uint256) (#1241-1243) sends eth to arbitrary user
Dangerous calls:
- address(_msgSender()).transfer(amount) (#1242)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

UNIC._splitlpToken() (#1397-1436) uses a dangerous strict equality:
- totalAmount == 0 (#1419)
Don't use strict equality to determine if an account has enough Ether or tokens.

Combination 2: Unchecked transfer + 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.
