0.6.3

Fixed:

• No need to duplicate asset for GitHub Updater
• Renamed verbose options for the GraphiQL Explorer settings (if any option had been disabled using v0.6.2 or below, the form needs to be submitted again, to use the new option names)
• Store plugin version to detect updates (plugin can be updated in many ways, eg: using Composer, so using hook "upgrader_process_complete" doesn't always work)
• Added option to disable admin notice in settings, and link in the admin notice
