DRB [DragonBattles] Token

Contract ownership is not renounced (belongs to a wallet)

DragonBattlesToken.setFee(uint256) (#973-975) should emit an event for:
- taxFee = _taxFee (#974)
Emit an event for critical parameter changes.

DragonBattlesToken.setFarm(address)._farm (#964) lacks a zero-check on :
- dragonFarm = _farm (#970)
DragonBattlesToken.updateDevAddress(address)._devAddress (#977) lacks a zero-check on :
- devAddress = _devAddress (#983)
Check that the address is not zero.

DragonBattlesToken._transfer(address,address,uint256) (#937-962) compares to a boolean constant:
-takeFee == true && taxFee > 0 (#956)
Remove the equality to the boolean constant.

Pragma version>=0.6.0<0.8.0 (#78) is too complex
Pragma version>=0.6.0<0.8.0 (#339) is too complex
Pragma version>=0.6.0<0.8.0 (#405) is too complex
Pragma version>=0.6.0<0.8.0 (#618) is too complex
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in DragonBattlesToken.withdrawBalance() (#1002-1007):
- (result) = owner().call{value: balance}() (#1005)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
