Previously, the documentation included hand-written tables for the
application, production, and technical starters.
This commit replaces the hand-written tables with tables that are
generated automatically from all of the starter poms, thereby ensuring
that the documentation is automatically kept up-to-date as starters
are added and removed. An extra column provided a link to each
starter's pom on GitHub has also been added to the table. This makes
it easier for users to see exactly what each starter contains.

Previously, the only starter that provided validation was
spring-boot-starter-web which included Hibernate Validator and
Tomcat's EL implementation. This left users writing non-web
applications to figure out the dependencies for themselves. They would
sometimes run into difficulties as Hibernate Validator's need for an
EL implementation would trip them up.
This commit adds a new starter, spring-boot-starter-validation,
which provides both Hibernate Validator and Tomcat's EL
implementation. spring-boot-starter-web has been updated to depend on
this starter rather than depending on Hibernate Validator directly.
Closes gh-2678
