Profile images need ALT attributes on Trac tickets

[sabernhardt]

Accessibility: images are missing alt attributes.

1. The Reporter and Owner images are also linked, so their alternative text should describe the link destination. To differentiate each of these links from its next link (to other tickets that the reporter has opened or that the owner owns), this text could include "profile" after the username.
2. For each comment, the profile image is part of the text link. Therefore, it does not need alternative text, but it still needs an empty alt attribute.
3. The Slack/IRC notifications could have empty alt attributes for their images as well. Alternative text like "chat discussion" might add some value, yet these images are mainly decorative.

• Add alt="[username] profile" for Reporter and Owner profile images.
• Add empty alt="" attribute for commenters' profile images and Slack/IRC notifications.

Props sabernhardt.
Fixes #6291.
Closes ​https://github.com/WordPress/wordpress.org/pull/70.

Just noting, that perhaps alt="${wporg_user}'s profile" would've been better, as now I'm looking at it on trac.w.org, alt="dd32 profile" isn't exactly good phrasing.

[sabernhardt]

Yes, including the apostrophe+S should be better than what I had. Thanks!
