1.9.10.9 General Update and Bugfix Release

This release defaults to Gradle 6.5; they keep releasing versions, so I am too. Compile times seem to be sometimes quite a bit faster with Gradle 6.5, though I mostly noticed a speedup when IDEA was set as the build tool, not Gradle, and running Gradle tasks. This updates and adds to the now-22 KTX libraries, as per #13 , and also updates several versions of other libraries (notably Formic, which had some extra changes needed, and anim8-gdx, which should be usable out of the box now). Thanks to @Mr00Anderson for finding a bug with shared modules and submitting a PR; there may be similar bugs in other previously-unused modules, like ios-moe, so I'm glad at least this type of thing may be easy to fix in the future. This also adds a line to the "legacy" LWJGL2 desktop launcher that gets rid of the highly-irritating error caused by successfully exiting.
