Refactor Chain actions arguments

[2snEM6]

Expected behavior

• Use named parameters instead of an array for better readability. For example:
  this calculateSupply: action => blockReward.calcSupply(action.height), instead of this calculateSupply: action => blockReward.calcSupply(action.params[0])
• Improve redundant code on modules/chain.index.js for actions declaration.

Actual behavior

Chain actions currently present the following issues:
Arguments are passed from actions interface to logic in form of an array which is confusing for the developer.
Actions declaration code on modules/chain/index.js seems redundant.

Steps to reproduce

Which version(s) does this affect? (Environment, OS, etc...)
