Contructor args in arguments.js

[tmsdkeys]

Right now, the arguments.js file enables devs to define constructor args arrays. It assumes that the application will alwyas either inherit UniversalChanIbcApp.sol or CustomChanIbcApp.sol and have dispatcher / middleware as their first contructor arg.

It lets devs define additonal args in arguments.js, while constructing a concatenated array with the dispatcher/mw when deploying, but arguably this is confusing.

Could look into different ways of ensuring constructor args are correctly added...

Closing for now, I feel like this is working
