Pull Request for Issue #126

Summary of Changes

Change the do/while patterns to better address the issue of Blank line between do/while

Testing Instructions

Run a Joomla-PHPCS test against a Repo with no blank line between do/while. There should not be a testing failure requiring a blank line between the do/while.

Finally got around to testing this (sorry). Didn't end up fixing the issue. I ended up adding this to the ControlStructureSpacingSniff and this did work:

if ($tokens[$trailingContent]['code'] === T_WHILE)
{
    if ($tokens[$stackPtr]['code'] === T_DO)
    {
        // DO with WHILE.
        return;
    }
}

Same type of check exists there already for an if statement with else.
