NewFeatures: Chronological entries

New: linktocomments renderer

This is a little new renderer that creates a link to a page in the view necessary to show comments. In turn, this has caused the 'your comment has been posted' template page to be tarted up so that it uses it, thereby letting people who have posted comments see them in the page they go to.

(I have decided not to have it link to the comment section of the page, just on general principle. I may change my mind about this.)

New: feed-max-size and feed-max-size-ips

This is all because LiveJournal has undocumented size limits on incoming syndication feeds, limits that DWiki can easily blow past. Since I actually wanted LiveJournal to be able to get syndication feeds from me, DWiki has grown two new configuration settings.

feed-max-size is an integer kilobytes. It is a rough limit on how large any feed can be; once DWiki generates a feed that is this many kilobytes or larger it stopps adding more entries, regardless of the setting for atomfeed-display-howmany. If unset, there is no size limit.

feed-max-size-ips restricts feed-max-size to the whitespace separated list of IP addresses or tcpwrappers style IP address prefixes (eg '66.150.15.' to get all of 66.150.15.*). Syndication fetches from other addresses will behave as if there was no feed-max-size.

Strictly speaking, feed-max-size limits only the size of the atom::pages or atom::comments output to that size. Whatever else is tacked on to make up a feed (hopefully not very big) will add some extra size.

Moral: undersize feed-max-size a bit. For LiveJournal, the limit is apparently 150 kilobytes (currently), so setting it to '120' or so should provide a comfortable safety margin.

Although I'm not entirely fond of this (to put it one way), the documentation has been updated appropriately, making this feature more or less official.
