phar['blah.php']->isWritable() works now

Hi, There were some rumblings about wanting a way to detect whether a specific file/archive was writeable. I made some small changes to the way we detect this when the ini setting is changed, and added a test. Now the existing isWritable() from SplFileInfo always works properly for Phar. In addition, is_writeable/is_writable work, as does stat and related functions, all of which were actually broken should one ini_set() phar.readonly to another value. http://news.php.net/php.pecl.cvs/10330 One step closer to satisfying the API grumblings :). We need some assistance from Mac OS X experts, changes are needed to make it compile on Tiger (and, apparently, on some Leopard systems that upgraded from Tiger). Thanks, Greg
