[plt-scheme] Continuation handling in web-server

There is a macro anchor-case in the file 
plt/collects/web-server/servlet-helpers.ss,
but it is not exported or documented or supported since we couldn't 
agree on
the appropriate interface.  Shriram's remarks about attaching the 
action to the
form instead of the button is the basic problem that leads to demuxing 
on the server.
