I know that I can't be the only person that has needed a stand alone editor
for GLS files. Attached is my initial run at converting the scene editor
into a standalone application. I've put a few features into this as well
that require it to be built in Lazarus 9.23+ with GLScene 101+.

Download size: ~10Mb - No idea why its this big but the application
exe itsef takes up most of the download space.
