[bcat/news/web/am] Implement news applet, proper TLV return, external web browser URL and qlaunch app sorting (#3308)

This pulls eden releases changelog & text from our github releases.
We don't store the msgpack file but rather generate them in-memory for the News Applet.
Uses cache folder. Files generated are:
- cache/news/github_releases.json
- cache/news/eden_logo.jpg
- cache/news/news_read

Additional changes:
- Proper TLV returning for online web applet, to open external URL
- Add applet type `LHub` to properly close, as it also uses TLV return
- qlaunch app sorting, adds another cached .json to track last launched app timestamps and sort them accordingly
