Improve URLSpy filtering

[ddworken]

Any URL containing the string ".jpg" will not be displayed when URLSpy is enabled. E.g. www.jpg.daviddworken.com will not be listed. This is an edge case, but should still be addressed.

• Rather than checking if URL contains ".jpg", instead:
  • Strip URL of all arguments.
  • Check if URL ends with ".jpg"

Filter out ad URLs.

• Generate a list of ad websites/domains.
• Filter URLs to check if they are on any of those domains.
