Upgraded PHP 5.4.29 and 5.4.13.
Fixed bug with compile helper where path was hard coded for PHP 5.4.  Now correctly adjusts for PHP 5.4 or 5.5.  Change is to strip off the full path for zend_extension settings when version is >=5.5 (not necessary any more).
Updated regex so that it's more flexible.  Now the leading path is optional.
Updated index files for lucid and precise builds.
