Better detect the config dir in Drupal installations.

From IRC, my monologue:

00:51 < Yaroon> Oh, guys, I noticed my cron jobs werent running...
00:52 < Yaroon> And I think I got another improvement in how civicrm works within Drupal.
00:52 < Yaroon> CiviCRM only suggests civicrm be installed in sites/all/modules
00:52 < Yaroon> But it's often a good idea (as we always do here at Krimson) to install modules either in contrib/ or custom/
00:53 < Yaroon> So we deploy everything under sites/all/modules/contrib/ and thus sites/all/modules/contrib/civicrm
00:54 < Yaroon> But this is what cli.php does to find the config dir:
00:54 < Yaroon> if ( strpos( $currentDir, 'sites' . DIRECTORY_SEPARATOR . 'all' . DIRECTORY_SEPARATOR . 'modules' ) !== false ) {
00:54 < Yaroon> $confdir = $currentDir . '..' . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . '..';
00:54 < Yaroon> So it checks to see if sites/all/modules is in the path...
00:54 < Yaroon> And then it decides the confdir is up 3 folders... not caring about however far down the path your civicrm might be installed.
00:55 < Yaroon> In our case it's under modules/contrib and not modules... so CiviCRM doesn't go up far enough.
00:55 < Yaroon> This is better I think:
00:55 < Yaroon> $confdir = preg_replace('/sites
' . DIRECTORY_SEPARATOR . 'all
' . DIRECTORY_SEPARATOR . 'modules.*/', 'sites', $currentDir);
00:56 < Yaroon> Replace the sites/all/moduleswhateverelsefollowsinthepath with: sites
00:56 < Yaroon> And you'll get the path down to sites (in which it goes down into default/ a bit further on and finds civicrm.settings.php)

So! in bin/cli.php change line 72 and 73 from:

// seems like this is in drupal5 dir location
$confdir = $currentDir . '..' . DIRECTORY_SEPARATOR . '..' . DIRECTORY_SEPARATOR . '..';

to:

// seems like this is in drupal installation, the confdir will be /your/path/to/drupal/sites/
$confdir = preg_replace('/sites
' . DIRECTORY_SEPARATOR . 'all
' . DIRECTORY_SEPARATOR . 'modules.*/', 'sites', $currentDir);
