Better automatic detection of platform-specific jars

[imagejan]

It would be desirable if the updater could better detect platform-specific files and only install those relevant for the current platform (while still allowing uploading for all platforms, of course).

As an example, here are the files shipped by the LUMoS update site, including platform-specific versions of several artifacts:

• mkl-(linux|macosx|windows)*.jar
• mkl-dnn-(linux|macosx|windows)*.jar
• nd4j-native-*.jar
• openblas-(linux|macosx|windows)*.jar

@imagejan this feature actually exists already but isn't really documented. After entering webdav credentials to upload, the side panel in Advanced mode becomes editable. This allows entering extra metadata about any file.

Under the platform section, you can enter one of the platforms known by the updater (linux32, linux64, macosx, tiger, win32, win64) and then upload the file to your update site. Then that file should only be managed by the updater when that platform is considered "active" (which is based on... a number of things?... including launchers detected).

At the least, we could add this to the wiki

Thanks for the clarification, @hinerm!

IIUC, that means that the maintainers of the LUMoS update site have to make that change manually so that users get just the files required for their platform, right? (/cc @tristan-mcrae-rochester)

I guess this issue becomes then: "Better automatic detection of platform-specific jars", as I think it would be useful if the updater can detect common patterns for platform-specific jars automatically, without requiring explicit information of the maintainer uploading the files to the update site.
