add code for proposals and gateways

[bassjobsen]

@a1300 please give an example of file and line number with wrong ident, because of for me it seems that the indetation is the same as the original files?

@bassjobsen github doesn't render the whitespace in code, but I saw that it was off, because github is using another tabspace width.

If you install this browser extension: render-whitespace-on-github you can also view it in the browser.

Please only use TABS 👍

P.S: I configured Visual Studio Code to render whitespace:

@bassjobsen I reviewed your pull request. I have only very small change proposals:

1. Proposal.js Line 72 1.1 Variable keys is not used. Variable can be removed
2. For the propsal.upvote function, it would be easier to pass the transactionId as a variable, instead in the options object 2.1 same for proposal.activate
3. In proposal.js please rename 3.1 activate -> activateProposal 3.2upvote->upvoteProposal 3.3 Maybe you could also provide the functionrevokeProposal`
4. For initgateway and I would make the name optional. Instead of hardcoding xxxxxxxxxx. You could make this parmaeter optional.

@a1300 About the renaming of the function activate -> activateProposal, that's more clear indeed. Th reaason i didn't name it activateProposal is that it is alread in a file called proposal.js. About the proposal.revoke, yes you're right about that, i'm waiting for a response on https://github.com/AschPlatform/asch/issues/224#issuecomment-416205654 .

And finally about the harded xxxxxxxxxx i will check that. In fact it mean the code of asch requires this parameter (not) optional and does not use it.

@bassjobsen regarding the renaming: Normally I would also think that the file is called proposal.js and we don't need to name the function activate -> activateProposal but it is somehow misleading that in the proposal.js part are many gateway functions. So I thought we could make it perfectly clear.

I like that you structured the code like the asch-core repo 👍

Regarding the proposal.revoke: You could implement the revoke function and the gateway_update_member function. And if the proposal.unvote function gets implemented, you can provide another pull request!

https://github.com/AschPlatform/asch/blob/develop/src/contract/proposal.js

const VALID_TOPICS = [
  'gateway_register',
  'gateway_init',
  'gateway_update_member',
  'gateway_revoke',
]

I only told you about the hard coded xxxxxxxxxx because I saw it in the database. It is not very aesthetically pleasing that every init_gateway proposal has the same name 🙂
