[FIXED JENKINS-41825] Display an informative message, rather than a Groovy exception, when View.getItems fails.

For some reason, Bulgarian translations included a gratuitous newline between key and value, which core/move-l10n.groovy does not yet grok.

This help text points to a very old redirect which is only editable in our
infrastructure Puppet code (which will at some point in the distant future be
removed).

Changing to jenkins.io/redirect means that the destination of this redirect
is easily modified by pull requests to
https://github.com/jenkins-infra/jenkins.io

Considering all the verbiage updates that happened last year, this reference
appears to have been missed and as such can be confusing to newer users.

- In the context menu, the 'post' flag was set iff 'requiresConfirmation'
  was set, even though they're independent (e.g. Prepare for shutdown
  requires the former but not the latter)
- /manage screen: The icon (t:summary) does not support POST or
  confirmation links, but was set to not link only if no confirmation
  was required (i.e. POST links did not POST when the icon was clicked
  -- now the icon is not clickable as a workaround)
- /manage screen: All links requiring confirmation did POST, which masked
  the fact that the 'Reload from disk' link wasn't set up to require POST
  (it was only broken in the context menu). Now, confirmation and POST are
  separate flags, and 'Reload from disk' link now requests POST.
