Proposed build upgrade

[David Jencks]

Geronimo has recently had some build problems related to camel and  
whether the camel snapshots are timestamped or not.  Although we fixed  
these by deleting some obsolete timestamped camel snapshots, deploying  
non-unique snapshots to apache nexus is not recommended.

In order to fix this I suggest upgrading to the apache 6 pom and  
adopting its conventions where appropriate.  I also recommend using  
some automated checking such as the ianal plugin.

I've opened https://issues.apache.org/activemq/browse/CAMEL-1766 with  
the changes I'm proposing.  I think I'm a committer :-) so if this  
meets with approval I'll see if I can commit it.

Note that the ianal plugin already found one blocking legal problem in  
camel-examples-spring, see https://issues.apache.org/activemq/browse/CAMEL-1765 
..

thanks
