Fix php-syntax-propertize-extend-region to extend END as well.

Previously, the function would only extend the START of the region. If
the END of the region falls within a HEREDOC, syntax highlighting
might be incorrect.

Tweak PSR-2 style by adding (substatement-open . 0)

PSR-2 states:

  Opening braces for control structures MUST go on the same line, and
  closing braces MUST go on the next line after the body.

However, in the event that the brace does go on the same line, do not
indent it.
