Rewrite mailcap handling.

Add a class that encapsulates the handler and is responsible for
managing the temporary file, if one is needed.

Use this class for both rendering inline content and displaying
attachments externally.

External attachments are now wrapped in an asyncio task that is added to
a pool of tasks managed by ui.
