Incorrect Order Downloading / Installing

[Ziugy]

Having a list of installers with the Lumin installer in the list fails to properly install the Lumin component because of download and install order.

Install starts by downloading only Lumin before the editor and other components and then attempts to install Lumin which then fails since the editor was not downloaded and installed first.

Commands to repro below. (Assumes fresh install.)

IMO this issue blocks #164

[StephenHodgson]

Wondering if this was an issue before Lumin was added?

Is it an issue with the order in general? I just added it to the end of the list, and implemented the corresponding component checks.

[jwittner]

Ah, yes, it is unrelated to Lumin. We return in order of the enum, but that assumes you aren't installing the core installers from other platforms.

[jwittner]

Thinking we should process all the contents of the pipeline to determine components that are missing, then put the platform installer at the front, then install. Thoughts on that?

[jwittner]

Workaround

Pass all the installers to the -Installers parameter and the platform installer will be selected first if available.

Note: We'll make this simple pipelining work across platforms in the near future without any sorting on your part.

[StephenHodgson]

If you ensure you select and install the component matching the OS first, then install all the rest of them, you won't see this.

I think this is also related to #162. We should likely include the editor platform by default based on the detected OS
