Posting a script to stop and start a Mac's NTP service

As part of a discussion on Twitter
(https://twitter.com/rtrouton/status/499919358806999040), I realized
that I hadn't posted my NTP restart script. Posting it now, along with
a README.

Updating Sparkle feed link in install_latest_oracle_java_8

Oracle apparently forgot to update the Sparkle feed for Java 8 Update
11 when they released Java 8 Update 20. Even though Java 8 Update 20 is
now out, the latest version available via Java 8 Update 11's Sparkle
feed is still is Java 8 Update 11:

https://javadl-esd-secure.oracle.com/update/mac/au-1.8.0_11.xml

To fix this, I've updated the install_latest_oracle_java_8 script to
use Java 8 Update 20's Sparkle feed:

First Boot Package Install now includes installation error reporting

I'm updating the copy of First Boot Package Install included with
create_vmware_osx_install_dmg, as part of following up on a First Boot
Package Install pull request by Matthew Kweskin
(https://github.com/mkweskin), I've updated First Boot Package install
so that it now reports whether an installation has succeeded or failed.
This error reporting is in addition to the error logging that is added
to /var/log/install.log by OS X's installer tool.
Moved the create_os_x_vm_install_dmg files to their own repo.

I've moved the create_os_x_vm_install_dmg files to their own repo and
left a README for folks looking in the former location in
rtrouton_scripts.
