[Feature suggestion] Option to render remote contents with user consent

[martgil]

Description: A FlowCrypt Android app user has expressed interest in a feature that allows loading remote content in their emails - Ideally, they might be looking for an option which can be set whether to render remote contents (which would be disabled by default).

For now, all content is filtered by the app. Also, we disabled JavaScript(for security reasons). This issue should be discussed.
