1.9.10.11: Big Stretch!

This adds one major feature (if you're using a HiDPI screen) -- you can now resize the window and stretch text accordingly, allowing the text to stay legible on high-resolution displays. It also includes a requested Kotlin compatibility change (using runtimeClasspath instead of compileClasspath in the jar task, which changes nothing for Java, but makes Kotlin projects usable as JARs). The JGLFW target is gone; from what I can tell it hasn't been updated in several years and most of it was merged into LWJGL3 anyway. VisEditor and the associated runtime have been deprecated since 2018; they aren't included in gdx-liftoff anymore. The LML-family dependencies are updated to a 1.9.10-compatible SNAPSHOT version; use them at your own risk, but they don't change very often and can probably be considered stable enough. Various other libraries had minor updates.
