The `--noreplace` argument to `emerge` is generally coupled with
`--newuse` or `--changed-use`, and can be used instruct Portage to
rebuild a package only if necessary. Simply checking to see if the
package is already installed using `equery` is not sufficient to
determine if any changes would be made, so that step is skipped when
the `noreplace` module argument is specified. The module then falls back
to parsing the output from `emerge` to determine if anything changed. In
check mode, `emerge` is called with `--pretend`, so it produces
different output, and the parsing fails to correctly infer that a change
would be made.
This commit adds another regular expression to check when running in
check mode that matches the pretend output from `emerge`.

When running in check mode, the *portage* module always reports that no
changes were made, even if the requested packages do not exist on the
system. This is because it was erroneously expecting `emerge --pretend`
to produce the same output as `emerge` by itself would, and attempts to
parse it. This is not correct, for several reasons. Most specifically,
the string for which it is searching does not exist in the pretend
output. Additionally, `emerge --pretend` always prints the requested
packages, whether they are already installed or not; in the former case,
it shows them as reinstalls.
This commit adjusts the behavior to rely on `equery` alone when running
in check mode. If `equery` reports at least one package is not
installed, then nothing else is done: the system will definitely be
changed.

* Refactor code to be more robust. Run main logic inside a try {} catch {}
block. If there is any error, bail out and log all the command output
automatically.
* Rely on error code generated by chocolatey instead of scraping text
output to determine success/failure.
* Add support for unattended installs: (`-y` flag is a requirement by
chocolatey)
* Before (un)installing, check existence of files.
* Use functions to abstract logic
* The great rewrite of 0.9.9, the `choco` interface has changed, check
if chocolatey is installed and an older version. If so upgrade to
latest.
* Allow upgrading packages that are already installed
* Use verbose logging for chocolate actions
* Adding functionality to specify a source for a chocolatey repository.

* Removing pre-determined sources and adding specified source url in
it's place. (@smadam813)

puppetmaster was used to determine if `agent` or `apply` should be used. But puppetmaster is not required by puppet per default. Puppet may have a config or could find out by itself (...) where the puppet master is.
It changed the code so we only use `apply` if a manifest was passed, otherwise we use `agent`.
This also fixes the example, which did not work the way without this change.

# Run puppet agent and fail if anything goes wrong
- puppet

puppet may be configured to operate in `--noop` mode per default.
That is why we must pass a `--no-noop` to make sure, changes are going to be applied.
