Possible beta-launch ready

Major reorganization and upgrade to documentation. Moved
zzTpkcUserDirName into each TPKC-user-directory (build-procs using it
are untested). TPKC-build output (AG) files now imported to three
locations ("build_proc_tech_info.html#import3"). Need to test-build and
then live-build tp_frsh_instl, and jeffy.
