Added PreRelease, Source parameters and fixed a missing parameter declaration

[DailenG]

• Most are just adding PreRelease
• Added Source support for some that choco actually supports it
• Fixed missing AskForConfirmation parameter declaration
• Updated function documentations in the script files (not Docs folder)

I removed one instance where chocolatey was declared as the default source because in some cases, such as several of my clients, the default chocolatey community repo is disabled and local proxy/connector is used instead with a different name

did not do a version bump, fyi

Thanks for that. I didn't even thought that the default source could be removed or blocked.
