Overwrite UPGRADE.textile with wiki copy
Make maven-gpg-plugin use gpg-agent
Update wikidoc commit pointer
[maven-release-plugin] prepare for next development iteration
[maven-release-plugin] prepare release 0.4.2
Remove call to JRE-7-only library method
Make maven-gpg-plugin ignore detached sig files

This prevents the creation of worthless "foo.asc.asc" files when
building signed release artifacts multiple times in succession without
an intervening `mvn clean`.
Tweaks to RELEASING and gh-pages update script

Collected during the 0.4.2 release
Control maven-scm-plugin version (1.9)
Merge commit '7df580ea559c79de0adcf71089b667ff6e2ae9e9' into titan-accumulo-0.4.2
Move Titan version to 0.4.2.
Update profile name in deb/rpm package scripts

The maven build profile formerly known as titan-release is now known
as aurelius-release.  The scripts that build debian and redhat OS
packages still referred to the profile as titan-release, which no
longer exists and has no effect; references updated.
Restructure pkg-tools filtered resource dir
Make pkg-tools clean.sh tolerate missing tmpdir
Make debian package rules use mvn --also-make

Changing into the titan-dist/titan-dist-all subdirectory and
attempting to build only that module fails if its peer and parent
dependencies aren't already installed in the local repository.  The
debian package rules script used this technique and would fail on a
pristine local Maven repo.  This commit uses Maven's -pl/--projects
and -am/--also-make options to build titan-dist/titan-dist-all and all
of the modules on which it dependends (but nothing more).
Update rpm specfile and RPM build.sh script

Changed README.txt to .textile and tweaked Maven invocation options
Locally install titan-dist-* test jars

These test jars contain Expect-based zipfile tests.  They formerly
weren't installed in the local repository; now they are.  They still
aren't deployed.
Build only zip (and not tar.bz2) distro archives

Centralized the format lists for all distro files into
titan-dist/titan-dist-parent/pom.xml
Shorten Accumulo configuration namespace key.
