The StatusInfo has a new details field. The StatusUpdater puts either the
reponse from the health endpoint or the exception message in the details.
This allows us to see the details over time (via the journal) and also to
use `em in a bit more mail notifications.

The managment.ssl.* properties needs to be taken into account when they
are explicitly set and the managment.port differs from server.port

fixes #333

With this commits the server no longer depends on the client. The
classes for the clients are moved to de.codecentric.boot.admin.client
package.
Since the perspective on applications is totally different from client
and server the model has been split apart.

What means this for users:
1) The client is no longer a transitive dependency for your admin server
you may need to add it explicitly to your dependencies, respectively
jolokia-core in case you're using discovery and want to use the jmx-bean
interface

2)In case you have cutomised parts of the client you need to reflect the
package change.

fixes #332

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.

closes #312

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.

fixes #309

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.

closes #306

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.
