Subject: [PATCH] Set chawan as default browser and add mailcap integration

- Set BROWSER env var to prefer chawan over other browsers
- Enable chawan features: cookies, referer headers, auto-redirects
- Add custom search with just-bangs-lite (C-k keybinding)
- Add M-o keybinding to open current URL in default GUI browser
- Add mailcap integration to open images with imv using curl pipe
- Create imv-mailcap wrapper script for seamless image viewing
