Fixed number parsing for --port.

[Windows81]

Normally, utilising oct-server -p 81 will print the message:

Open Collaboration Server listening on localhost:NaN

This pull request attempts to fix that.

Refer to https://www.npmjs.com/package/commander#custom-option-processing for this implementation.

Hey @Windows81, thanks a lot for the contribution!

Before we can accept your changes, please sign the Eclipse Contributor Agreement (ECA) with the same email that was used to create the commit. This is a simple CLA that simply keeps legal trouble out of the way :)

This will also automatically pass the check on your other PR over at #154.

I took a look at it. However, as this is my first time contributing, I need to make an account with Eclipse.

Problem is that I'm not currently able to get the CAPTCHA to validate properly.

My email address is [email protected] in case that's needed.

[msujew]

Have you signed the ECA with [email protected]? Because the commit was created with the [email protected] email address. Please either sign the ECA with this email or amend your commit to change the email address to the one that was used to sign the ECA.

[Windows81]

Thanks for the clarification. I actually haven't properly signed the commit with either. Hold on.

@Windows81 Did you have a chance to try it again?

[Windows81]

Might try again soon.
