Using older composer version syntax to support older builds of composer

[mtdowling]

This commit updates the SDK to use older composer.json syntax to support older builds of composer. This converts ^ usage to ~ and || usage to |. I'm not sure if | is exactly equivalent to ||, but it seems to be based on testing it locally.

👎 composer has supported this for over 6 months now.

[mtdowling]

I appreciate that. Unfortunately we need to make this change for now.

I was hoping you could inform me on this: do you know if the syntax of | and || are equivalent?

[GrahamCampbell]

I'd have to check the source to be 100% sure.

Could we do >=5.3,<7?

[mtdowling]

Kind of, but it's really fragile. For example, what if we only wanted 6.1 and up because of a new required feature? Or 6.0.1 and up for a bug fix?

I would do ~5.3||^6.0.1 or ~5.3||~6.0.1||~6.1 if you want to avoid the caret sign.

[GrahamCampbell]

~5.3||^6.0.1 wouldn't avoid it, and would result in a parse error.

[GrahamCampbell]

~5.3||~6.0.1||~6.1 would work fine.

[hannesvdvreken]

what parse error?

[GrahamCampbell]

The one you get if you use a really old verion of composer...

[hannesvdvreken]

what you said is what I said then.

[GrahamCampbell]

Well, i can't remember the exact error off the top of my head. If you're interested try it out I guess.

As per @GrahamCampbell's suggestion, I've update the version constraint to >=5.3|~6.0.1|~6.1
