Use the Enforcer plugin to ensure our dependencies are compatible with Java 5 #234

Use the Enforce Bytecode Version Plugin to ensure our dependencies are 
compatible with Java 5:

http://mojo.codehaus.org/extra-enforcer-rules/enforceBytecodeVersion.html

The java6 package should obviously enforce Java 6 compatibility. App Engine 
also requires at least Java 6.

We attempted to do this once, but ran into the following problem:

The Enforcer plugin crashes with a NullPointerException. This seems to be 
because we specify version numbers in <dependencyManagement> instead of 
directly on the dependencies. 

The following thread appears to be the issue we're facing as well:
