Add detection for Steam4C2

[TobiX]

Some reference to the SDK, such as the developer site or a wikipedia article.

Steam4C2 is a (popular?) plugin for Steam integration into Construct 2 games. See https://www.construct.net/en/forum/scirra-website/asset-store-36/steam4c2-plugins-114191

• Construct 2 in now EOL
• Author has been MIA since some years
• Since the Construct 2 asset store is now offline, nobody can buy the plugin anymore

SteamDB links

• https://steamdb.info/app/873200/ (not detectable, in ZIP)

Possible way to detect it

The following files (or a subset of them) will exist:

File name	Flags	Type	Size
package.nw/Steam4C2-linux32.node		node	165.50 KiB
package.nw/Steam4C2-linux64.node		node	162.90 KiB
package.nw/Steam4C2-osx32.node		node	153.38 KiB
package.nw/Steam4C2-osx64.node		node	166.94 KiB
package.nw/Steam4C2-win32.node		node	255.00 KiB
package.nw/Steam4C2-win64.node		node	314.50 KiB
package.nw/Steam4C2.js		js	1.17 KiB

PS: While looking for more examples, I found some older plugin for the same feature (called greenworks, see https://www.construct.net/en/construct-2/addons/83/greenworks/versions) in some games (https://steamdb.info/app/1066900/, https://steamdb.info/app/1111600/), which might also be worth adding:

File name	Flags	Type	Size
package.nw/greenworks-linux32.node		node	678.26 KiB
package.nw/greenworks-linux64.node		node	565.60 KiB
package.nw/greenworks-osx64.node		node	615.39 KiB
package.nw/greenworks-win32.node		node	927.00 KiB
package.nw/greenworks-win64.node		node	1.19 MiB
package.nw/greenworks.js		js	7.76 KiB

@diedyesterdaywashere It seems quite popular to pack Construct games, so that will make detection of any Construct middleware quite unreliable 😢
