In short, developers can use Godwoken v1 the same way as other ethereum compatible chains, all that has to be done is to switch the network to Godwoken. The polyjuice-provider web3 plugin has been removed in v1.

Purpose
This PR unified layer2 fungible token representation as u256.
This PR also changes the decimal of CKB, in layer1 CKB is represented in 8 decimal, but when user deposit CKB into layer2, we changed the representation to 18 decimal. Thus, layer2 CKB can play the same role as ETH, developers can operate CKB as 18 decimal asset(like ETH) in their contract without modification. This change also improve the compatibility between Metamask and the native token CKB.
