Updated PackXZExtract to v1.0.1.
If no files are queued for extraction, the step is skipped.
The UI now shows some indication that the extraction is in progress.
The player count on the landing page is now functional. If the server cannot be reached, the label and value will change to SERVER and OFFLINE, respectively. This behavior can be modified.
When a user attemps to launch, the configured Java executable will be validated. If it is invalid, we will look for a valid installation. If no valid installation is found, the user will be prompted with an option to install Java. An option to decline needs to be added. If they choose to install, it will download, extract, and update the executable in the config. The game will then be launched.
Also added progress tracking for asset validations, as they can potentially take a bit longer. Showing progress assures the user that the program isn't stuck or broken.
Fixed an issue with concurrency when there are no downloads queued on launch. Added support for static function execution in AssetExec. Fixed a binding issue in uicore.js caused by delayed div loading. For now the solution is just hard coding in the value, will probably switch these two a css file later on. Included the launcher's x64 runtime directory in Java scans.
Mojang fallback cannot be implemented due to limitations of decompressing large lzma files in node.js. This can probably be worked around by packaging with some command line binary, but it honestly it not worth it.
Static utility functions have been moved. Functions which handle Java downloads will be moved next. AssetGuard is becoming a lengthy file, to cope with this I've added region comments so that specific sections can be collapsed and expanded when needed.
