Bug: Endless loop trying to include whole page in WEBTOPICLIST

It will not happen often: If someone tries to include a whole page in the WEBTOPICLIST, an endless loop occurs and twiki consumes all cpu-time and RAM, because the included page has a WEBTOPICLIST ...

As I noticed, includes in normal text stops after 4 levels of inclusion, but there seems to be no endlessloop check in this case.

Test case

In WebPreferences:

 * Set WEBTOPICLIST = %INCLUDE{"WebIndex"}%

Follow up

Bounced because this still exists, and it constitutes an obvious vulnerability for a DOS attack on a public twiki.
