Now correctly including generic.styl in all other sheets. This was
quite a mess to figure out because of the way Stylus handles
imports/requires. IIRC, Less doesn't work this way, but, of course,
Less is much more limited than Stylus.
Having a single extra space indenting a child selector (5 spaces instead
of 4) caused the following, correctly indented sibling selector to be an
unparented selector, turning "#hnmain a" into "a", causing it to apply
to all A elements in the page. And there were no errors from styl.
Wow.
