Add docblock indent fixer

Ensure that docblocks for class methods and attributes are indented if present
EDIT: Ensure that any docblock uses the same indentation as the documented subject, regardless the type
We have in mind efficiency and consistency. So... please, be efficient and consistent.

If you really, really want to have tnat `$index` and `$index -1` then change `foreach` into simple `for`, but I think that would be changed in future back into `foreach`
