Webstorm plugin not installable on Windows because of ? (question mark) in folder name inside ZIP file

[JoelDSmith]

This is currently not installable on Windows (both from within Webstorm, or via downloading and installing from disk). This is because of the ? (question mark) present in the plugin folder inside of the ZIP file, which is not a valid filename character on Windows.

After I downloaded the plugin manually, I renamed the folder inside the ZIP to not have the question mark, and then the manual install from disk worked for me.
