Show username and email in tooltip when hovering over a full name

[Ryan J Ollos]

When [trac] show_full_names is True the user's full name is shown. The username and email could also be shown in the tooltip when hovering over the full name, like ​th:UsernameDecoratePlugin does. The email address would be obfuscated or not shown depending on the settings and user permissions.

I'll have to look at the code more closely, but presumably the ​UsernameDecoratePlugin would no longer be needed after this change, and could be listed as obsolete in TracUpgrade.

UsernameDecoratePlugin also has the following features:

• Gravatar, also proposed in #11068, and used on Wordpress Trac site (#11199)
• Author label can be customized with keys $username, $email, $fullname
• Author title can be customized with keys $username, $email, $fullname

​tipsy is used for the tooltip styling.

Adding customizability for author label and title might be option overload for Trac, but adding a title, and possibly the Gravatar, seem like nice enhancements. It's worth considering for Trac 1.3.x.

With the work done in #7339, we can probably make a simpler version of UsernameDecoratePlugin, assuming we are now using Chrome.authorinfo in all the places that an author needs to be formatted in Trac. Also, Environment.get_known_users is cached (#11868) and can return a dictionary ([14247]). If UsernameDecoratePlugin wasn't adding a Gravatar it wouldn't need to implement ITemplateStreamFilter and could continue to work beyond Trac 1.4 (​[th 15213]).

Would there be any objection to having Trac communicate with the ​Gravatar service? If necessary we could try to implement it through a Component in tracopt.

If implemented at all, make it optional defaulting to off.

Living in a corporate environment I wouldn't be too happy to have my internal bug tracker communicate with external servers possibly disclosing information about users of the bug tracker.
