Adds a Configuration Editor to the Settings section for Umbraco 8 with capability to edit all files in the /config directory plus the root Web.Config file. The root Web.Config file will be backed up with a date-stamped extension on save.
[x] Expanded configuration filters to include all configuration files under App_Plugins (json, xml, config)
[x] Moved alert banner for Web.config so it doesn't overlap the actual editing area obscuring it.
[x] Remove empty folders
[x] Import proper Ace Editor xml view instead of using Razor.
