Fix

• Plugin now installs and loads the plugin without requiring the user to take additional steps

Changes

• New logic for how plugin is updated

new logic for plugins

if repositoryRoot/manifest-beta.json exists
    use repositoryRoot/manifest-beta.json for release information, ignore repositoryRoot/manifest.json
    copy repositoryRoot/manifest-beta.json to plugin folder, renaming it to manifest.json
else
    use repositoryRoot/manifest.json for release information
    copy Release/manifest.json to the plugin folder if it exists. If it doesn't exist, use the repositoryRoot/manifest.json

main.js and styles.css copied from the correspondencing release version depending upon the above logic
