Option to disable UpdateCheck

[sambonfire]

Prerequisites

Unity Out of date github for unity plugin

Description

When launching Unity, the github plugin checks if it is out of date, and if so it prompts the user to upgrade with a popup window.

There are a couple of issues with this:

1. This popup is displayed even when we run Unity in headless mode (for example, when we want to generate a build)
2. We don't want artists to ever accidentally click that button and do the upgrade themselves

Ideally, we would just like a version of the UpdateCheck that would just write a warning to the console to let us know if the plugin is out of date, or else just disable the update check completely (we are happy to do it manually).

Steps to Reproduce

1. Install an old version of the github for unity plugin
2. launch unity
3. notice the popup window prompting you to upgrade

Expected behavior:

Ideally, we'd like an option to change this to just disable it completely or to just log to the console.

Actual behavior:

There is currently no way to disable this window that I'm aware of.

Reproduces how often:

100%

I have to look more into the update check. I vaguely remember that the setting is stored in either the users local or remote profile. It makes sense that you would want to disable it at a repository level.

In regards to your builds, you are going to need a bit more than that. If you set the environment variable GITHUB_UNITY_DISABLE. It will prevent the plugin from loading at all.
