upgrade groovy to recent version

old:

<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy</artifactId>
<version>1.1-rc-2</version>
</dependency>

new:

<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>1.5.6</version>
</dependency>
<dependency>

i tried it with the trunk and the 'script console'
seems to work fine, but i dont know where else
groovy is used in hudson ...
