App Cast Generator 2.8.4

• Fixed being able to detect version string such as app.7.0.0-beta1.tar.gz (previously strings like app.7.0.0.tar.gz worked, but if you stuck on -beta1 or similar on the end, it would stop working, which is unexpected behavior, despite the fact that app.7.0.0 is not really a version string with the word app in there. Now both work.)
