Prior to this commit, a dependency on a local file was not being
packaged by the Gradle plugin. This was a regression from the behaviour
in 0.5.0.M6 caused by the move to using a ResolvedConfiguration and
ResolvedArtifacts (4f677bec) to gain access to an artifact's type so
that non-jar artefacts could be filtered out. Since then, the approach
to filtering has been changed (38585bf3) and access to an artifact's
type is no longer needed.

This commit updates ProjectLibraries to restore its use of a
FileCollection rather than a ResolvedConfiguration when getting hold of
the files in a configuration. This means that the resulting jar will
now include dependencies that aren't resolved, such as those that are
provided as local files. The filtering that is applied to the files
is unaffected by this change and only files that are zip files will be
included.

User can specify the content type in external properties now, optionally
ommitting the charset (since that is duplicated). If charset is not
appended by user Spring will do it.

Apparently yaml.org prefers .yaml, but the internet seems
to be more aligned with .yml, so I guess we should support both
out of the box.

I preferred /etc/bash_completion.d (since it mirrors the actual
preferred deployment of the scripts on my OS). Maybe the MacBoys
have a different point of view? Anyway the docs now point to the
actual script location.

Apparently springloaded 1.1.5 was released to Maven Central with a
different groupId than to repo.spring.io. It would have worked in
milestones because the repository was declared.

When the user sets management.contextPath=/admin the Jolokia
endpoint gets mapped to /admin/jolokia, but that the path stripper it uses
internally makes a false assumption about the form of the request path.
The fix is simple (just use a smarter search for the endpoint path in the
request path).

There was already a reflection hack in place for logging the local
port in Jetty 8/9. It wasn't being used for the getPort() method
for some reason, so that needed to be fixed.

Since it is not parsing XML it makes no sense to be validating
and it would cause exceptions when importing "namespace"
features. This brings the Boot usage of the bean builder inline
with that in Spring Core.
