Automatically sets tinker_panic 0 when $is_virtual is true.  This
configuration enables ntpd to cope with large clock skews, such as occur
when a VM guest is suspended and resumed.

Update Modulefile for 0.1.0 release

(#14497) Add tinker_panic option for ntpd

Added support for Amazon Linux

is_virtual fact must be checked using a string comparison.

The previous logic would resolve true if the is_virtual fact was
defined. This meant that on servers where is_virtual was defined as
"false", the vm-only snippet was still inserted into the template.

Fix is_virtual check in ntp.conf templates

Puppet-lint was complaining about "ensure found on line but it's not the
first attribute on line 109".  Trivial fix (swapped the ensure and the
name).

Also, the README didn't mention Debian or CentOS, but the comment block
in init.pp did.  I added both to the README.  I happen to be using this
with Debian unstable, but I haven't tested it extensively enough to say
"yep, this works".  It, however, works for me.

fairly trivial fix to make puppet-lint stop complaining, and a doc update

0.2.0 is a backwards compatible feature and bug-fix release. Since
0.1.0, support for Amazon Linux was added, fixes for style were
implemented and support was added for tinker_panic. tinker_panic
will default to on when the fact is_virtual is true.
