New features:
- Each History entry now has a 'Check status' button for checking live job status. The button also repairs the live status update by recreating the alarm.
- Per-job 'Remove' button + a 'Clear finished' button that removes all completed/failed/cancelled records. A 'Cancel' button for ongoing jobs has also been added.
- Auto-resume crawl jobs upon browser restart.
- More robust fallback ladder before printing PDF. Always saves best attempt at scraping/crawling and falls back to PDF is all options are exhausted.
- A 'Test connection' function has been added to the Preferences, allowing the user to check the HTTP status of their endpoint.

Fixes:
- Fixed a bug where the 1st scrape/crawl instantly fails even if add-on is correctly configured.
- Fixed a bug where 'include links' appears to do nothing. Links now appear in a separate .txt file next to the scraped content.
- Fixed a bug where crawl polling would falsely report dead jobs regardless if the job simply failed or was cancelled.
- Fixed a bug where writer would hang indefinitely if download was interrupted.
- Internal debug now always keeps the last 100 records in storage, even when file logging is off. The preferences page now has a 'Download debug log' for accessing these.
