don't try to load view cache entries that have view cache disabled

if the cache is disabled we know already by the <kwc1 vs. <kwc2 placeholder
remove uneeded preloadClasses

we can remove those because of fullPage cache
don't call SessionToken class, instead ask if there is an authed user

avoids one more class getting loaded
one class less to load on fullPage cache hit
load classes starting with Kwf/Kwc with absolute path

should improve performance as the path doesn't have to be looked up from include_path
preload less classes
Use processInput of Opt-Component instead of implement own

Improves performance
set supportsHttps without having to access config
cache used simpleCache backend in generated setup
get urlType only once
set memache host and port in generated setup

avoids two config reads from apc plus including one file
fix clearing simpleCache
shutDown checkpoint only once
fix ccw
