Show plugin startup errors on metadata screen
Add a visual indicator which links to or has a label that contains any plugin startup errors on the metadata page.
Given that they are swallowed to prevent the apphost from crashing it is not always obvious unless you check the operations metadata.
From v4.5.7 (now on MyGet) the number of Startup Errors will appear in X-Startup-Errors HTTP Response Header (visible when viewing HTTP Responses) and when in DebugMode a warning banner will appear on the /metadata page.
Perfect, thanks Demis.
