Added: src/bin mediator.jelly
Log:
added an experimental mediator jelly script to show how we could initialize maven
once then use jelly to mediate between the POM beans, properties and Ant tasks.
here we use jexl to access the pom and use pom.getProperties() to get Ant style
properties.
Note if we didn't use '.' as a separator between names in the properties life would
be easier, we could
use ${maven_compile_deprecation} for example.
this example doesn't show how to do plugins in a better way, though that should be
able to be done on the client side, invoking stuff before or after the body of a
target.
