Sitemap

[IoIxD]

After @samhza changes the library to Arikawa as he's insisted, there needs to actually be a sitemap.xml document. This is the most important part, because without one, Google only indexes the index page.

The sitemap, which will be updated once a day, will need to list all variations of the following:

• dfs.ioi-xd.net/
• dfs.ioi-xd.net/guildID
• dfs.ioi-xd.net/guildID/chanID
• dfs.ioi-xd.net/guildID/chanID/postID

Additionally

• The xml files need to be (optionally) compressed as gz files.
• The entries in the files should have appropriate dates set.
• The contents of each file should be cached for up to 30 minutes.

#7 may need to be mentioned here. I don't think that the sitemap needs to reflect such a change but it might.

(there's still work to be done i'm just merging it into master so that the person working on this code after i go to bed can merge into his code)
