2.3.0: Merge pull request #5 from WordPress-Phoenix/develop

• Add ability to turn off auto-loading for VIP hosting
• Add plugin_data and version
• Fix scoping issue with plugin activation
• Simplified plugins_loaded init by moving into static run function
• Removed vendor autoload loader from main plugin
• Had to skip version 2.1 and 2.2 as several plugins were hot-patched with those version and we don't want to run into those.
• Moved filename back to a dash, since VIP requires a dash for CI phpcs rules, works fine since plugin uses vendor autoload by classmap anyways
