Add auto-configuration for application Restarts. Restarts are enabled
by default (when not running from a fat jar) and will be triggered when
any classpath folder changes.
The ClassPathRestartStrategy additional customization of when a full
restart is required. By default a PatternClassPathRestartStrategy with
patterns loaded from DeveloperToolsProperties.
Closes gh-3084
Add Restarter class that can be used to restart a running application
when underlying class files change. The Restarter is automatically
initialized via a ApplicationListener and automatically detects
classpath URLs that are likely to change (when not running from a fat
jar).
See gh-3084
Add a parent last classloader for use with application restarts. The
classloader provides a layer on top of the regular classloader to
contain the classes that might change when an application is restarted.

Add a filesystem watcher that can be used to inform listeners of
changes (add, delete, modify) to files in specific source folders.
The implementation uses a background thread rather than the WatchService
API to remain compatible with Java 6 and because WatchService is slow on
OSX.
See gh-3084
Add auto-configuration to automatically apply properties that make
sense during application development. Currently the single property
`spring.thymeleaf.cache` is set to `false`.
