Add support for the /loggers endpoint from spring boot 1.5.x. With this
change log4j2 (and every other logging backend supported by spring boot)
is supported in the logging view.
The old implementation will be kept a while, so that the clients aren't
forced to migrate.

Display the version for groups. For multiple versions the lowest (by
lexical compare) gets chosen and a ellipsis is appended.

Change the application list to a fixed table layout to prevent it from
overflowing in the window and limit the info column to a max width.
Also limit the info column in the detail view.

fixes #316

Annotating the applicationRouteLocator bean with
@ConfigurationProperties yields the wrong configuration metadata.
Instead do a explicit properties bean to get correct metadata.

With this commit the support for Turbine is completly revised. From now
on Turbine is supported via a separate module and is integrated as top
level view.

This CompositeRouteLocator allows extensions to add custom RouteLocators

To easily add new mvc controllers (e.g. from extensions) a new
annotation `@AdminController` is added.

To fix the IE11 css quirks we need to use the ngStyle directive
instead of just using expressions inside regular style attributes.

fixes #280

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.
