Feed Titles should include forum/topic

Feed titles are not descriptive and don't differentiate between eachother.
When a feed is specific to a forum, it should have the name of the forum in the feed title. For example if the feed is for your own phpbb announcements, the top of the feed is currently
<title>phpBB.com</title>
<subtitle>Home of phpBB</subtitle>

Should be something like

<title>phpBB.com - announcements</title>
<subtitle>Read me first before posting anywhere!</subtitle>

Where the subtitle is extracted from the forum description.

Same should apply to 'new topics' feed and to topics in general.
