Released AIXF: Thread Top 2.0.0

Tested on 2.3.7 and 2.2.17 (see info tab). Please test before installing.

##Features
This add-on provides a **“Top threads” view**, ordered by the first post’s reaction score (upvotes minus downvotes). It is a minimal scaffold that installs cleanly, with no schema or XML.

---

## Usage
- **Global Top:** `/aixf-top`
- **Forum Top:** `/aixf-top/forum?node_id=NN` (replace `NN` with the forum’s node ID)

---

## Notes
- Relies on the **first post’s `reaction_score`** (XenForo maintains this automatically).
- No database schema changes; uninstall is clean.
- Works on XenForo **2.2+ and 2.3+**.
- Optional: create Upvote (+1) and Downvote (–1) reactions for best effect.
