Stacky comment now includes PR status as of last push (#23)

Updated emoji logic match stacky inbox categorization:
    - 🚧 Construction for draft PRs (work in progress)
    - ✅ Check-mark for approved PRs
    - 🔄 Loading for PRs waiting on review (has pending review requests)
    - ❌ X for PRs waiting on author action (no pending reviews, likely needs changes)
