Newsletters
Added support for theme customizations in newsletters.

Optimized the HTML generated for newsletter content to reduce rendered email content weight by approximately 25%.
Campaigns
Segmentation: Added a new segmentation criteria to target readers based on whether they’re known to have a user account. If a reader has logged into the site, they’re known to have a user account, even if they subsequently log out.
Analytics: Added segment names to event_category labels for each prompt.
Added the ability to designate inline prompts as “undismissible”. Undismissible prompts cannot be closed by readers, and will not be suppressed by global plugin suppression options.
