Add git ignore
Fix compilation issue
fix typo in hello3 target name
Add cobertura:init target (fetch and configure cobertura ant task)
configure easyant and ivy namespaces in module.ant
introduce cobertura:instrument target
 - delete previous coverage datafile
 - do instrumentation
 - contribute to test runtime classpath and prepend instrumented classes

'run.test.classpath' has been found using project man command (easyant -listParameters)
'target.test.classes' and 'target.test.integration.classes' were found also found  with project man command (easyant -listProperties)

Note that those elements are defined in 'abstract-test:init' target, so coverage instrumentation must depend on it
