Fixed bug which prevented mods with declared extensions in their identifiers from being loaded.
Synced distribution.json with remote.
Updated electron-builder.
Updated readme to include information on beta testing.
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.
