Either set flyway.[url,user,password] or create a DataSource
@Bean and mark it @FlywayDataSource.

New feature in Spring Mobile (user preferences per site).

Fixes gh-946

See gh-948

Instead of *always* needing to pull auto-import dependencies
from the master parent pom, we now allow normal @Grab-style
module specifications, e.g. "io.ratpack:ratpack-groovy:0.9.2"

* fixdoc:
  Fix table row format in documentation

when server.servletPath is set we need to add prefixes to
the security filter paths.

Fixes gh-945

This affected @ConfigurationProperties binding whenever there
were multiple PropertySources (from any source) in the
Environment and mor ethan one carried a value for a particular
key. The rules for override are clear in Environment.getProperty()
but they were being violated by the PropertySourcesPropertyValues.

Fixes gh-916

Open up AutoConfigurationPackages.set(...) to allow programmatic
configuration of base packages.

Fixes gh-924

Fix MalformedURLException warnings caused by Tomcat 8 adding additional
URLs to the TomcatEmbeddedWebappClassLoader.

Add JasperInitializerLifecycleListener to call Tomcat 8's
JasperInitializer which is now required for JSP rendering.

Fixes gh-919

spring-instrument-tomcat is deliberately not included as it is only
required with Tomcat 6 and Boot uses Tomcat 7

Boot’s auto-configuration for FreeMarker and Velocity relies on Spring’s
support for them that’s packaged in spring-context-support. Only
auto-configure them if their respective Spring classes are on the
classpath

Fixes #940

Rename SimpleDataSourceHealthIndicator to DataSourceHealthIndicator.

Update Health and Status objects to be immutable, update the existing
builder methods to return new instances and add static convenience
methods to Health.

In addition I added some convenience methods to ServerProperties
(servletMapping() and servletPrefix()) for manipulating the
servlet path as provided by the user (e.g. normalizing it into
a valid Servlet mapping path for the DispatcherServlet).

Deprecate setNamingstrategy() and log a warning letting people know
that they should use `naming-strategy`.

Issue #928

fixes #930

In 1.0, the property spring.jpa.hibernate.namingstrategy could be
used to configure Hibernate's naming strategy. This was at odds with
most other configuration where binding to namingStrategy would require
a property with some indication that it was two separate words, for
example: naming-strategy, naming_strategy, or namingStrategy

This commit adds a new setter, setNamingstrategy, to JpaProperties so
that an app that was using namingstrategy in 1.0 continues to work
in 1.1.

Issue #928

Closes #906

Refactor and rework several areas of the Gradle plugin:

- Refactor package structure into functional areas and configure each
  area separately via a new PluginFeatures interface.
- Convert BootRunTask to extend RunTask rather than attempting to
  find existing RunTasks.
- Simplify agent integration by no longer needing specific BootRunTask
  code.
- Update the repackage task to consider the `mainClassName` property
  in addition to `springBoot.mainClass`.
- Automatically set `mainClassName` when calling `run` or `runBoot`
  from `springBoot.mainClass` if there is one.
- Ensure that explicitly defined `main` options on JavaExec tasks always
  take precedence.

Sync the explicit setting with 'project specific settings' in case
the eclipse plugin is not used.

to make it more simple to implement HealthIndicator

Since we upgraded Aether we now have the native JreProxySelector
available so we don't need to keep a copy ourselves.

Closes #792

Prevents large SPNEGO headers from causing server errors for example.
Added the property to ServerProperties.
