Request #20165 Adding configurable spacing
Add NOWDOC tokens to the list of HEREDOC tokens to treat them equally

NOWDOC and HEREDOC are basically the same but aren't treated like that.

Also, ignore "space before ," when the token before the whitespace is
a HEREDOC or NOWDOC.
Updated changelog + unit tests + made the error location more accurate
allow upper case NULL class constant for PSR-2
Generic LowerCaseConstantSniff and UpperCaseConstantSniff now ignore class constants
Merge branch 'master' of https://github.com/Astinus-Eberhard/PHP_CodeSniffer
Fixed some problems with checking spacing when none exists + unit tests + coding standards + changelog
