This reverts commit e99d2199d8b613f6099eb3fd577b9700b4050b8f.
The main spring-boot project should not have compile scope dependencies
to any org.slf4j artifacts.
Inherit default profile activation for spring-snapshot-build in the
spring-boot-starter-parent from the spring-boot-parent.
Allow sample projects to work correctly in eclipse.
Rework main build POM to be an aggregator pom that does not inherit
from any parent. Introduce new spring-boot-dependencies module to
act as a parent for both spring-boot-starter-parent and
spring-boot-parent.
