[phpcs] Fix blank line detection
[phpcs] Fix blank line detection

Squiz.WhiteSpace.SuperfluousWhitespace has problems detecting blank
lines in functions when used together with the PSR2 standard.

More information: https://github.com/squizlabs/PHP_CodeSniffer/issues/600

This commit fixes that issue by restoring the original behavior.
It also adds rules for function spacing because the sniff mentioned
above does only work within functions.
