tracker should ignore resolutions in quoted text

[heycam]

mozilla/wg-decisions#443 is an issue that was automatically filed by @mozilla-apprentice after noticing a "RESOLVED:" within some quoted text. It should probably ignore quoted text (and perhaps any instance of "RESOLVED:" not at the start of a line).

And I guess this is because it's looking at the issue comment as plain text rather than Markdown or HTML, and in plain text the quote marker doesn't get converted into a > or anything.

Parsing Markdown / HTML doesn't sound fun here. Maybe we can remember resolution text that we've already handled on a given issue, and avoid filing a new issue if we've already seen the resolution before.
