(GH-599) Restrict calls to choco.org to https

This proved the changes required to ensure that client communicates with
chocolatey.org using HTTPS.
(GH-600) Give maintainer heads up about moderation

This keeps maintainers from guessing about what might be happening. It also
adds a self-policing call that maintainers should ensure they can receive email
from chocolatey.org and the google group without ending up in the spam folder.
(GH-571) Use process id instead of name

When waiting for a process to exit, use the id of the process as name may cause
errors if the name if is incorrect versus the actual process name. ID is
deterministic so should have less chance for error.
(GH-558) quote path on batch fallback
(maint) add kickstarter message
(GH-577) use default credentials if available.
