Allow Application Objects to scan email message HTML

Currently when Application Objects use the "Transform URLs into an application object" option, they can only match plan URL content.

For example, and AO detecting URLs with https://example.com/user/:id, would match Mathilde's profile, but not Laurent's in the example below;

---
Take a look at the following profiles;

• Mathilde - https://example.com/user/123

• Laurent - user profile

---

The URLs are both valid and match the specified pattern, but because Laurent's is hidden in a hyperlink, it is not accessible to the AO.

Allowing matching on plain and hyperlinked URLs should increase the utilization and match success on AOs.
