Merge branch 'PSR2-1.0' into PSR2-2.0

Browse Source 
* PSR2-1.0:
  Fix indentation phpcbf did not fix.
  Remove PSR2.Methods.FunctionCallSignature.SpaceAfterOpenBracket exception.
  Use phpcbf to fix PHP code to ruleset.
  Ignore coding guidelines in ANSI switch block.
  Base code sniffer ruleset on PSR2 rather than PEAR.
  Update PHP Code Sniffer to 2.3.3
