Feature request: Better subject lines for e-mail notifications about new forum posts

[Xkeeper0]

Relevant piece of code:

RAWeb/app/Mail/CommunityActivityMail.php

Line 173 in f461e14

case ArticleType::Forum:

Currently, the email subject line is "New Forum Comment from (user)"; the subject line does not say what thread the comment is in. This also causes some email clients (in my case, GMail) to group email notifications by user, even if they are about posts in different threads.

The e-mail itself includes the username, so removing it from the subject line won't remove any critical information.

This also applies to Game Wall comments (which should mention the game in question), and possibly other notifications.
