x/gov: Allow description to have newlines

[ValarDragon]

Summary

We should parse \n in descriptions to allow printing newlines. I think this would make the output format better in the CLI.

Proposal

Add a pre-processing step when proposing txs to parse \n's in the description as newline characters.

Can we just parse all escape codes a la echo -e?

Alternatively, we could standardize on a simple text format for descriptions, e.g. Markdown.

[ValarDragon]

I'd be cool with using markdown. If we do that though, then I think the CLI for governance proposals should allow for reading from files, and we should perhaps get the title from the first line or first occurence of # . That should be left for a seperate proposal imo.

We should parse escape codes in the literal descriptions in the CLI (as you described), regardless of markdown support

Mhmm, why not have the proposal accept a possible file that adheres to a structure? (e.g. JSON w/ title description, etc...). Parsing first # seems a bit janky.

Sounds good to me. Would you like to make a seperate proposal issue for reading from files?

Sure thing!
