Prior to this commit, the schemaZip Gradle task failed to find Spring
schema files on MS Windows due to path separators hard coded to forward
slashes that are not compatible with the Windows operating system.

Consequently, a full build failed on Windows since the distZip task was
not able to locate the zipped schema archive that the schemaZip task
failed to create.

This commit fixes this by updating the schemaZip task to search for
schema files using backslashes as well as forward slashes.

Prior to this commit, there was some ambiguity surrounding semantics
for @Autowired constructors and `required = true`, especially for
multiple @Autowired constructors.

This commit improves the documentation in the Javadoc for @Autowired as
well as in the reference manual.

Prior to this commit, if the user configured an empty path for the
targetRequestPath property of a FlashMap, the FlashMapManager threw a
StringIndexOutOfBoundsException when saving the output FlashMap for the
next request.

This commit fixes this by skipping the decoding and normalization of an
empty target request path. An empty target request path is therefore
effectively treated as the root path.
