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

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.

closes #237

With this commit urls form the /info endpoint are deteceted and rendered as
links.
The downside is to make that work I had to drop the collapsible info section in
the overview list and replaced it with an resizable/scrollabe <pre> section.

otherwise it gets mixed up whith the standard html title attribute

With this commit the icons from FontAwesome are used. To achive this the
webpack css-loader is used and the location for the module.css has slightly
changed.
Also I removed the ugly sidebar (what a short life) and added a slim navbar at
the top for the detail views.

With this commit it is now possible to add your own ui modules to the servers
classpath and they will show up in the ui.
Every module needs an "entry" script file in the classpath located under
`META-INF/spring-boot-admin-server-ui/<modulename>/module.js`.
The module is be implemented as angular module and needs to be added to
the global `uiModules` list.
The spring-boot-admin-server-ui-activiti module is a simple sample for
adding a application view but it is also possible to add main-views.
Please have a look at the events module in spring-boot-admin-server-ui/modules.

Please note that the internals of the ui can change anytime.
