Fix: message_generation dependency for standard messages

[jubeira]

This fix updates message_generation dependency to kinetic range in template to generate messages properly.

See https://github.com/rosjava/rosjava_mvn_repo/issues/27 and https://github.com/rosjava/rosjava_mvn_repo/issues/32.

For the record, I verified that messages are now generated with a dependency on message_generation from [0.3, 0.4) instead of [0.2, 0.3).

Example POM for a message generated with new template:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

  <groupId>org.ros.rosjava_messages</groupId>
  <artifactId>geometry_msgs</artifactId>
  <version>1.11.9</version>

      <artifactId>message_generation</artifactId>
      <version>[0.3,0.4)</version>
      <scope>runtime</scope>
    </dependency>
    <dependency>
      <groupId>org.ros.rosjava_messages</groupId>
      <artifactId>std_msgs</artifactId>
      <version>0.5.10</version>
      <scope>runtime</scope>
    </dependency>
  </dependencies>
</project>

Note: perhaps the messages should be updated in mvn_repo with this fix to avoid conflicts when using maven as the issues specified above point out.

Thank you very much, @jubeira . And yes, you're right, I will update the messages in the maven repo as soon as I get a chance.

:+1: Thanks! Perhaps this step should be written somewhere to take it into account next time... Having these values hardcoded in the code is somewhat difficult to maintain. Whenever a new release bumps the version, that value should be updated for consistency.

I agree @jubeira . I just added it to this doc that we used with @stonier last time around.
