This changes the hard-coded display name in the breadrumb bar to match
the localized message used in Configure Global Security/Access Control

provide localization for HudsonHomeDiskUsageMonitor.getDisplayName()

May not suffice: a fatal error may simply be thrown later on.

"Jenkins is loading" page gets set up before Jenkins instance gets
initialized.

these messages were purged in 772bd8f6
for being unused, but they are actually active.

This change determines in the current items parent is the Jenkins
instance. If so, behavior is as before. Otherwise, link to parent
and use the label 'Up' instead of 'Back to Dashboard' similar to
Folders Plugin.

The previous implementation of 'disable remember me' just removes the
checkbox from the UI. Users still can set the parameter using a web
browser extension, or patch the login page using a Greasemonkey script
and keep using the feature. And just after the feature is enabled, users
still might be able to use it if they loaded the login page early.

This change prevents that by checking the current configuration and, if
'remember me' is disabled, ignoring any headers set.

In this case display the reported exceptions differently and be done with it.

thanks to kutzi for spotting this.

This reverts commit b354bca0.

Unfortunately, Afrikaaans is the default selection of the language, and
some people apparently contributed translations without selecting the
proper locale. I see some Hebrew text in here, which was easier to
distinguish because it uses an entirely different character set.

But I have to assume other locales are mixed in here as well.

I'll remove the default language from the translation assistance plugin.
But in the mean time, we don't have anyone who's capable of reviewing
this, so I'm forced to roll back.

Otherwise a REST API user needs to scan through a couple pages of HTML to find the actual message.

This behaviour is noted in MapOptionHandler.

Changed so that each nobuilt, aborted and disabled will use icons with unique names. The Icons used in this patch are just a copy of grey.
