Update web.xml modification for auto-reconfiguration 1.0.0

This change updates the web.xml modification behavior to support auto-
reconfiguration 1.0.0.  The modification no longer makes any change to
the application context configuration XML files or Java classes.  It
now only adds three ApplicationContextInitializers to the
configuration.  In cases where there is no web.xml file, auto-
reconfiguration 1.0.0 will use a web fragment to configure itself.

Upgrade auto-reconfiguration version

Previously, the auto-reconfiguration JARs for Spring, Play, and Play
JPA were pinned to an old version of auto-reconfiguration.  This
change updates those patterns to use the latest in the 1.x line.

Version updates

This change updates the versions of Ruby and the dependencies.  This
time round both rubocop and rspec required extensive changes for
compatibility.
Improve Windows packaging experience

Previously, when the DownloadCache was used on a Windows machine, it
could not read and write files properly.  This was due to it using the
default system encoding which differed from the expected UTF-8.  This
change updates the DownloadCache to always read and write files as
binary in order to get around the encoding issue.

Previously, when files were cached by the DownloadCache, the file
names were escaped to ensure that there were no forward slashes in
them.  On Windows, this escaping is not sufficient, as colons must be
escaped as well.  This change updates the escaping to cover this
additional case.

Immutable CachedFiles

Previously, the CachedFile always behaved as if it was mutable, even
in situations where it was working against an immutable cache.  This
resulted in situations where a combination of intermittent network
connections and read-only file systems would cause an attempted
direction creation that would fail.  This change enhances the
CacheFile such that it can behave in both a mutable and immutable
fashion.
