* Initialization for new repos AUTOMATED.

* Adding new users AUTOMATED.
* Update docs for the new, more simplified installation processes.

* blackbox_addadmin now adds keys to the keyring for you.
* Unified #! lines to "#!/usr/bin/env bash" so it works better on FreeBSD.
* BUGFIX: (BugId#1) blackbox_update_all_files.sh expects hg, fails for git.
* BUGFIX: (BugId#2) blackbox_postdeploy.sh assumes certain directory layout.
* BUGFIX: Temporary files aren't deleted.
* NEW FILE: bin/blackbox_initialize: Automates enabling BB for a repo (creates directories, files, and updates .gitignore).
* NEW FILE: bin/blackbox_removeadmin: Automates removing an admit.
* NEW FILE: tools/confidence_test.sh: A battery of tests to verify operations.
* NEW FILE: bin/Makefile: Automate package creation.
