Standard token bridge (#988) 

* Remove abstract token gateway and deposited token implementations

* Further simplification of bridge contracts

* Standart token bridge and L2 token implementation

* Fix spacing

* Implement case when a bad deposit happens to a nonexistent L1<>L2 token pair

* Use SafeMath in common token bridge accounting

* test(contracts): fix finalizeWithdrawal test

* fix(contracts): use SafeERC20 on token deposits

* Rename OVM_L1ERC20Gateway to OVM_L1ERC20Bridge contract

* Rename iOVM_L1ERC20Gateway to iOVM_L1ERC20Bridge contract

* Cleanup gateway to bridge rename

* Use OZ SafeMath

* Rename local variables in OVM_L2DepositedERC20 from gateway to bridge

* Merge ETH and ERC20 bridge contracts

of being reused in custom ERC20 bridges

depending on which asset is being withdrawn

Add a new Standard Token Bridge, to handle deposits and withdrawals of any ERC20 token.
For projects developing a custom bridge, if you were previously importing `iAbs_BaseCrossDomainMessenger`, you should now
import `iOVM_CrossDomainMessenger`.
