(chocolatey#2591) Add headers to limit output commands

When a user asks for limited output from Chocolatey, it is not uncommon
to pipe that output to `ConvertFrom-String` or `ConvertFrom-Csv` and
manually add headers to get back an object. This allows for getting a
header row back so that the end user doesn't need to add their own
headers and discern what they are.

This also adds a StringResources static class that allows us to store
constant strings in and use them across the code to reduce duplication.
