Add page caching support to the framework. Before processing
the templates, the framework should check whether the
requested page is already in the cache (the cache folder is
specified by the constant CACHE_PATH in 'const.Paths.php').
Each component (WebBox or WebObject) should be cached
separately because this reduces the size of the cache. If there
is a component that cannot be cached, because it interacts
with the DB, then the framework will parse and render it.
