 * Test against other PHPs
 * Test on other webservers
 * Clean up internal HTML a bit
 * Clean up internal code.
 * Set refresh rates on a per-feed basis
 * Probably some other stuff
 * The "loading" page should do something happy so that when things
   are actually displayed, Magpie won't try to retrieve non-retrievable
   URLs anymore (right now it'll try to load it both times, which could
   be a bit problematic).
 * Some kind of AJAXy loading of feeds would be a nice alternative to
   the current loading-page scheme, so long as it can be turned off
   for folks who want to be able to look at Zort via a text browser.
