v2.0 B2 (2.0.2)

CHANGELOG:

- Fixed bug with "Custom Font Filter" (doFilters.js)
- Filters will now apply when reading a post via showpost.php
(doFilters.js / backgroundScript.js)
- Edited settings popup for better look when using lots of colour
filters (settings.html / style.css)
- Added a notification when extension is auto-updated (updateScript.js)
- Prevented users to edit 2 or more colour filters due to unexpected
behaviour when doing so (settingsScript.js)
