Fix comment for DisallowSpaceIndentSniff
Fixed bug #19969 : Sniffs with namespace not recognized in reports
Merge branch 'master' of https://github.com/squizlabs/PHP_CodeSniffer
Explaining a standard (phpcs -e) that uses namespaces now works correctly
Changed the way namespaces are checked as this is easier and more consistent with other parts of the code
Restricting a check to specific sniffs (phpcs --sniffs=...) now works correctly with namespaced sniffs
Add a few more generic sniff xml docs.
