Diversify URL schemes

[phseiff]

I want to overhault the way hashtags in the URL are processed by the website.

Currently, the URL phseiff.com/#foo leads to the essay foo.
And for every essay foo, a file is hosted under phseiff.com/e/foo and phseiff.com/essays/foo that redirects to phseiff.com/#foo.

I want the behavior to be like the following, instead:

• The URL phseiff.com/#foo leads to the essay foo.
• The URL phseiff.com/#bar/foo also leads to the essay foo, no matter what bar is.
• If foo is not a valid essay and scroll location, the hashtag is cleared (rather than just failing and leaving the hashtag as-is).

I could then easily add a list of essay-dirs to the builder (like e, essays, about), and for every essay-dir bar and every essay foo, a file is hosted under phseiff.com/bar/foo that redirects to phseiff.com/#bar/foo.
