Sage Xpress Versions Save

Adds support for Facades and Aliases, plus misc fixes.

• Facades for Illuminate's Blade, Config, Event, File, and View services.
• Facades for SageXpress Comments, Menu, and Sidebar providers.
• Overwrite Laravel Blade directive for @inject to set container to Sage.
• Fixes the Blade::if() method for those opting to work with Laravel version 5.5

Gets more in line with using Sage Container to register Providers via configuration. Similar to the way Laravel uses the Container to register Service Providers in during App bootstrap.

Adds the Schema Provider with accompanying Blade directive @schema().

This is the first release for Sage Xpress which includes:

• Blade Directives - Out-of-the-box and config file to add your own custom directives.
• MenuProvider - Config driven menu setup. Dead simple rendering with @menu.
• SidebarProvider - Config driven sidebar setup. Dead simple rendering with @sidebar.
