Dao.sol: Define BASE as iBEP20 instead of address

[code423n4]

Vulnerability details

Impact

BASE is defined as an address type, but is casted as iBEP20 in almost every instance within the Dao contract, and in numerous instances in many other contracts as well. It would therefore be better to define it as iBEP20 instead, to avoid casting.

Recommended Mitigation Steps

Change address public BASE; to iBEP public BASE. Castings of BASE to iBEP20 can be removed subsequently.
