Journal #2604

There, I've made some minor changes to lists (extending them) on the main page and navigation bar, and have added a little Journals page ? an extension of the Recent Journal Entries box on the index. A proper full browsable Journals section will be in TWHL3, of course, but there's no sense in coding it twice.

It took pleasingly little time to do it all, too. About forty minutes from start to finish ? and that's without common functions for sensible things like avatar-grabbing.
