Compilation error on master branch for 1.3.1

[ppodgorsek]

The code currently on the master branch as of 1.3.1 does not work, Maven throws the following exception:

[ERROR] Failed to execute goal on project spring-test-dbunit-sample: Could not resolve dependencies for project com.github.springtestdbunit.sample:spring-test-dbunit-sample:jar:1.3.0-SNAPSHOT: Could not find artifact com.github.springtestdbunit:spring-test-dbunit:jar:1.3.0-SNAPSHOT

This is due to the POM versions not having been updated to 1.3.1-SNAPSHOT after the last release.

Will be done in a maintained repository under ppodgorsek#3
