* Make it more foolproof

* Don't fail on non-XAR modules when verifying

* Put back automatic verification

* Improve Formatting, should be all ok now ;)

* Make format mojo work across all modules

* Fix test

* Disable auto check for now

* Hmmm we need new lines otherwise we get a compacted form... However need to find out why we get too many new lines now...

* Don't print new lines

* Fix potential issue and improve logging in case of error

* Improve Format Mojo by cleaning comment, minorEdit and defaultLanguage elements

* Add test: verify that the encoding is UTF-8

* Add test: verify that the default language is empty

* Add test: verify that the minor edit is false

* Add test: verify that the save comment is empty

* Improved test

* Format Mojo nows works (mvn xar:format to use it)
* Added an integration test to prove it

* Improve error reporting for Verify Mojo
* Started adding a Format mojo to help automate fixing errors and pretty print the XML (note: there's currently an encoding bug: the transformed file contains garbagged chars and I don't understand why...)

* Exclude Main.WebHome from orphan check + improve checking logs

* Make it easy for maintenance by using the parent's version in test projects
