Since the actuator mvc endpoint beans live in a child context when the
server and management port aren't the same, the admin client shouldn't
depend on those beans.

fixes #302

Add ES6 and SSE polyfills to support Internet Explorer 11 and Edge.
Using Edge the ui has all features like in Chrome / FF. For IE 11 the
desktop notifications aren't available.

closes #280

Since ES5 is supported on all major browser, it's safe to remove
es5-shim. Also Update the dependencies and use exact version strings.

With this commit objects are passed now correctly to jolokia. The
object's needs to be written in json, which is validated for well-
formedness.
From now on the attributes are read autmatically when the bean gets
selected and I fixed that errors weren't displayed.

fixes #301

The 'use strict' in the activit module affected the global scope and
broke the ui for some orderings of the modules. With this commit the
module is wrapped into a function so the global scope isn't affected.

fixes #294

Adds a button to enable automatic refresh of the details view. Also fixes the
uptime counter, which got currupted by the reload button.

closes #262

Instead of alway hitting F5 and do a full page reload, this adds a small button
to refresh the details view.

If server.address or management.adress is set use it's value to resolve the
hostname used for management-/service-url.

 * Since the hystrix.stream incorrectly handles HEAD requests we had to change
   the detection for the hystrix-endpoint to a GET request.
   Issue https://github.com/Netflix/Hystrix/issues/1369

 * We need to improve Zuul's SimpleHostRoutingFilter and SendResponseFilter to
   close the underlying socket when an error occurs when writing the response.
   I hope that the code can be removen when my PR gets merged.
   Issue https://github.com/spring-cloud/spring-cloud-netflix/pull/1372

Fixes #290

Updated linkifyjs to 2.1.2 which treats single quotes as punctuation and now
renders the detected links in the yml nicely.

closes #282

Update to the recent spring cloud release.
Unfortunately the ZuulProperties now depends on Hystrix
classes so we need to add hystrix-core to the server
dependencies.

closes #281

With the fix for #260 we ignored all events from child contexts which turns out
to be wrong since the "main" application context is, in case spring cloud config
is used, is a child  of the bootstrap context. So we just act on the events from
WebApplicationContexts. After they're fired up the needed port information is
available.

fixes #277

In case a hystrix.stream does'nt sends any data and just a ping the endpoint is
not detecet correctly and the ui get unresponsive. The problem is that the sent
"ping:" chunk doesn't triggers the message event listener.
So instead we use a simple HEAD-request to get the header and status.

fixes #276

With this change the AbstractNotifier isn't specialized on status changes, but
the default behaviour for the existing notifiers isn't changed.
In addition the existing notifiers have been improved so that subclassing has
become easier.
To have existing notifiers acting on other events you need to override
shouldNotify().

fixes #270

fixes #269

closes #237

fixes #263

When includeing spring-cloud-netflix-hystrix-amqp to your application it looks
like that the ApplicationReadyEvent is fired twice (from main and child
application context). So we need to take care that only the events from the
main applications are taken into account.

fixes #260

Using an absolut url in $http.get doesn't work when the server.context-path has
been changed for the admin server. Like in all other places a relative url has
to be used.

fixes #256

Remove the activiti endpoint from the default set of proxified endpoints.
This aligns with the non present defaults for hystrix.

By using the netflix/hystrix-dashboard this module allows you to view the
metrics from hystrix/turbine in the spring boot admin server. This module needs
to be added explicitly.
