Moving definition of util_memoize_flush from memoize-procs.tcl to 20-memoize-init.tcl. server_cluster_httpget_from_peers proc was not defined when loading memoize procs. This issue is related to bug #2396.
Moved the bootstrap and installer stuff into their own mini-package, which let me clean up the loading of acs-tcl a bit and isolate all the bits of APM-knowledge required in the pre-acs-tcl bootstrapping process into a single apm file. In general, bootstrap.tcl is cleaner and easier to read.
