Delete session cookie on logout.

Resolves Issue #4, I think.
Give the session more time each time a restricted page is accessed.

Previously, a session would timeout one hour after the user logged
in.  This could be in the middle of an editing session, and work
would be lost.  Now the session is reset when the user hits the
edit page, so there will be no problem unless the user spends more
than one hour editing a single page.
Made redirects after login/logout more reliable and automatic.

The current uri and referring uri are now stored in parameters.
The loginUserForm function sets a cookie "destination" with the
referring URI.  After login (and possibly registration), the
user is redirected to this destination.
Version bump to 0.3.3.
Fixed regression for pages containing spaces.

This had to do with the use of withRequest rather than uriRest
in handle.
Remove destination cookie when no longer needed.
Deal properly with spaces in destination for logout.
