(docs) Tweak an unclear referent in keystores guide

Using "your" to refer to a new working dir seemed to imply that it had been
referenced before, and a user on IRC got confused.
Update: Change link to screencast list from blip.tv to official Puppet Labs account

The current MCollective video page has a duplicate version on the core puppetlabs.com site:

<http://puppetlabs.com/mcollective/screencasts>

In order to reduce the chance of duplicate content penalties, we want to make the version found on the docs site the canonical version and redirect traffic from puppetlabs.com to docs.puppetlabs.com. 

This change updates the link to the video list to use the YouTube account and playlist owned and maintained by PuppetLabs.com

Docs: Add more explanation about the complexity of networkConnector elements

When explaining this to the PE team, I was reminded of many many gotchas lying
in wait. This makes the doc more wordy, unfortunately, but I think it adds
enough explanation that it'll be easier to get these right.

(docs) Explain networkTTL attribute in network connectors

Existing docs seemed to imply that this was based on time, but it's actually
based on network hops.

22316 - MCO Plugin Packager produces more than one source artifact

In the past when invoking the plugin packager, multiple source artifacts
would be created and multiple builds would be run for every identified
package.

This commit changes the behavior of the plugin packager to only build a
single source artifact and perform a single build.

The ability to keep build artifacts after the build process has
completed successfuly or failed has been added by passing the
--keep-artifacts flag to the packager.

Naming internally to the packager has also been improved. Iteration is
now referred to internally as revision and the --iteration option has
been deprecated in favor --revision.

The #do_quietly?(true|false) method has been renamed to the more sane
 #perform_verbosely(true|false)

The #build_tool? method has also been renamed to #command_available?

22720 - --nodes 'nodefile' doesn't work on ruby 1.9.3

In the past the nodes option failed on ruby 1.9.3 because the input
value was replacing the discovery_options array with a string.

This commit appends the input value to the discovery_options array and
adds some additional testing for the Optionparser class.

16572 - deb pkg installs to a ruby-version independent dir

As newer debian/ubuntu releases default to ruby 1.9, mcollective-common
should install files to a version-independent directory.

/usr/lib/ruby/vendor_ruby/ has been in ruby's default path on debian at
least since lenny (2009).
