PHPCS-fixer hook

This release comes with a hook for phpcs-fixer.

small bugfixes

check copied, renamed and modified files as well

When using diff-filter at first, I probably thought it was about lines,
when in fact, it was about lines.

xliff syntax checker

This release slightly improves the syntax checkers output, and adds a new syntax checker for xliff files.

fix small error in the documentation

This is just to make sure the docs for stable are correct.

Move files that need copying to a separate directory

This is a major release because of a BC-break that will cause you to change a git configuration variable. It is not a big deal, but you must do it if you upgrade. More details in the upgrade documentation

small bugfix for the configuration script

The configuration script does not like subfolders in hooks folder. Avoid them for the moment.

syntax checker hook

• a syntax checker hook, which only works for php, but is easy to extend for any language
