www: implement generic help text

Begin documenting some basic help functionality.
I may tweak the anchor names of the various HTML endpoints
to be more consistent with each other (old ones will be
supported for a short while), so I'm not documenting
those, for now.

This may become part of a builtin key-value store for
basic texts, but this probably shouldn't become a wiki
engine, either.
