(#669) Make use of --include-headers

To ensure that the tab completion always works, regardless of whether
the alwaysIncludeHeaders feature is enabled or not, explicitly make use
of the --include-headers option on each execution of Chocolatey CLI.
This allows us to control what happens with the output, and knowingly
understand the headers that are output.

In addition, expand some options to use their default option values,
for example:

-r -> --limit-output
-h -> --help
