[Its now deprecated!] [GitHub issue #5653] Deprecate the Always condition

[Reborn]

Reasons:

1. It is decorative.
2. There is no real usage.
3. We don’t use it and we will never use it.
4. It misleads beginners to think that they need to use it at events in order to make something happen every frame.
5. The fourth reason deserves to be mentioned twice.
