Better diagnostics when missing HttpModule or MiddleWare

[bakgerman]

Uses ctor for middleware and httpmodule, and initializelayoutrender/initializetarget, instead of warning every time, as requested.

Resolves #954 and resolves #953

Maybe having the alert in the initialize-section might produce too many false-positives. Ex. loaded NLog configuration, but not yet setup http-pipelines with middleware etc.

Maybe it should be the on the first LogEvent where HttpContext is available.

Also could it become InternalLogger.Info instead of InternalLogger.Warn, and something like "NLogRequestPostedBodyMiddleware is not yet initialized, which is required by aspnet-request-posted-body.".

Changed to first log event

Think it looks great. Just have some small suggestions.

[bakgerman]

Thank you for the always good suggestions. Modified as suggested.

(Have you pondered, when it may be possible to work on items marked as 'breaking changes' in the issues list?)
