There are three means to configure Wickets configuration mode and they
are tested in the order given.
1) A system property: -Dwicket.configuration
2) servlet specific <init-param>
3) context specific <context-param>
The value might be either "development" (reloading when templates change) or
"deployment". If no configuration is found, "development" is the default. -->
