Strict run and add document metadata in runtime

[ruslan-mogilevskiy]

Hi @daveaglick,

First of all, thanks for the cool engine for static sites. Playing with it for a while and it looks very promising. Could you please guide me in the following questions:

1. I've enabled Strict mode for the bootstrapper:

Bootstrapper.Factory.CreateWeb(args)
   .AddSetting(WebKeys.Strict, true)

and according to the documentation I expected that Statiq will throw an exception in runtime or at least stop/exit when some error occurred but it didn't. By the error, I mean smth like an invalid LESS file content (thrown by dotless), etc. but Statiq just logged the error in the control when started and that's all. Q: How to terminate Statiq with a not-0 exit error code when something has failed on start?

2. Is it possible to add custom metadata to a document in run-time (in the pipeline code, etc)? I see that the document inherits IMetadata which is read-only. My goal is to add the metadata in one of my pipelines and process it in another.

Thanks.
