* respect count instead of listing all groups
* respect page parameter
* don't spew notice on undefined $id
* don't spew notice on undefined $group->homepage_url (dropped the element since there's nothing to go in it)

Merge tried to delete things that it seems it shouldn't, very confusing order. Hope rest of the cherry-picking isn't a problem.
Moved the various classes used by the Activity class to their own
files. There were >10 classes in the same file, with around 1500 lines
in the file. Just too big.
This change makes autoloading work for these classes, so also removed
the hard require in lib/common.php.
RSS feeds have the format
<rss><channel><item/><item/><item/></channel></rss>. The element named
$rss was actually the <channel> element, so I renamed the variable so
I wouldn't hurt my head.
First steps to parsing RSS items as activities. RSS feeds don't seem
to have enough data to make good remote profiles, but this may work
with some "hints".
* Subscription::start was sometimes passing users instead of profiles to hooks, which broke OStatus subscription notifications; now normalizing to profiles for processing.
* H-card parsing would trigger a lot of PHP warnings and notices in hKit. Now suppressing warnings and notices for the duration of the call to keep them out of output when display_errors is on.
* H-card parsing would trigger a PHP fatal error if the source page was not well-formed XML and Tidy was not present on the system. Switched normalization to use the PHP DOM module which is always present, as we have no need for Tidy's extra features here.
* Trying to fetch avatars from Google profiles failed and triggered a PHP warning due to the relative URL not being resolved during h-card parsing. Now passing profile page URL into hKit by sneaking a <base> tag in while we normalize the HTML source.
* Profile pages without a "Link" header could trigger PHP notices due to a bad NULL -> array(NULL) conversion in LinkHeader::getLink(). Now checking that there was a return value before converting single return value into array.
