Amend header to match checkstyle format

[scotty6435]

The checkstyle code status on this project has 1,634 issues, mostly because of one rule violation. Checkstyle compares the Java header to .codeclimate/header.txt but because " Bundle" is omitted, none of these match. I've updated the header on all java files for the main bundle but have not touched a few references in oakpal-checks. Please let me know if you want to add a qualifier to any of these and I can amend e.g. "ACS AEM Commons Oakpal Checks Bundle".

The pattern:

 ?\* ACS AEM Commons[A-Za-z ]* Bundle

Build status showing the issue mixed with other minor Checkstyle issues:

The proper header template file has also been applied across the whole bundle to standardise optional lines, add copyright start dates, remove rogue characters and to fix spacing between the header and the package line.
