Trying to fix releasing issues: Updated maven-release-plugin to 2.5, maven-gpg-plugin to 1.5
[maven-release-plugin] prepare release izpack-5.0.0-rc2
[maven-release-plugin] prepare for next development iteration
Updated Maven plugins needed for releasing to latest version (still compatible to Maven 2.2.1 and higher)
Removed configuration for Maven2Eclipse plugin, these settings can now be configured in Eclipse itself, not necessary to have them in the POM any longer
