Fix problem where test fails for some timezones (#566).

The ability to generate a UTC referenced log message seemed useful, so I added that to the log command.
Update log command manpage to reflect new --utc command, and also fix some typos.
Update exporting.rst

Fix a couple of typos.
remove the neo4j graph database as a direct dependency on CLI

Fix case where tests fail in some timezones
Use cli-app's dependency on web-app correctly.

Instead of depending on the maven-jar and maven-install plugins to create the jar
for the web-app module, instruct the maven-war-plugin to attach the classes jar
and make cli-app depend on it with the classes classifier.
tell web-app's pom.xml to also package up its classes as a jar inside WEB-INF/lib
Make geogit-console work properly with scripts and stdin/out redirects.

By making sure input is always read from the jline console, since
jline spawns a thread in order not to block during text reading
from the console, setting an "interactive" flag to false in case of
I/O redirects, and not adding interactive features like progress
reporting, colors in output text, command history, etc if not in
interactive mode.

comment out larger case for RevTreeBuilderTest.testResultingTreeSize() to speed up the build
make tests that didn't use TemporaryFolder use it instead of ad-hoc tmp folders
Exclude geogit-geoserver tests, they don't work properly with -Djava.io.tmpDir

The tests inherited from geoserver tests don't work properly if
java.io.tmpDir is specified (geoserver test infrastructure issue),
but this module is about to be removed anyways so no harm in disabling
the tests.
Allow to specify the tmp dir used for tests with mvn -Dtest.tmpDir=<path> ...
