1.0.0-alpha.29

• Moved a bunch of IBootstrapper extensions to Statiq.Common so they're available from extension libraries in an IInitializer.
• Renamed IConfigurableBootstrapper to IBootstrapper.
• Added a new IInitializer interface that can be used for library/module initialization (but only when using the Bootstrapper).
• Refactored the RenderRazor module to use the built-in service collection when possible.
• Added a new IServiceCollection.AddRazor() extension to register Razor services out-of-band.
• Refactored the ClassCatalog to Statiq.Common and exposed it via the IExecutionState interface.
• Added .WithSource() to the PaginateDocuments and GroupDocuments modules.
• Added a new Keys.Order key and made the OrderDocuments module support it.
• Added a keepExisting parameter to the GenerateExcerpt module.
• Removed some ambiguous IShortcodeColletion.Add() extensions.
• Added a bunch of Bootstrapper.AddShortcode() extensions.
• Added a new ForAllDocuments module that can act as a parent module to arbitrary child modules.
• Added a new If shortcode (#789).
• Added a new ForEach shortcode (#789).
• Added a TypeHelper.TryConvert() method that takes a target Type.
• Added support for "script strings" to metadata get extensions (if the key starts with "=>" it will be treated as a script and evaluated instead of getting the metadata value directly).
• Refactored IShortcode to return multiple shortcode result documents and concatenates their content.
• Modified CreateTree sort delegate to include the IExecutionContext and to sort by input document order by default (instead of path/file name).
• Added a IDocument.IdEquals() extension method.
• Added a IDocument.GetLink() extension method that calls IExecutionContext.GetLink().
• Added a IDocument.HasChildren() extension method.
• Added an empty constructor to OrderDocuments that orders documents by the Keys.Index value and then the file name by default.
• Added a IConfig.Cast<TValue>() convenience extension method.
