ZF-3752: Change command line arguments for Blogger.php sample to exclude extraneous '--'
Currently, the Blogger.php sample for Zend_Gdata lists the following as usage:
php Blogger.php -- --user=[username] --pass=[password]
The extra -- is extraneous and doesn't follow Unix conventions, so should be removed:
php Blogger.php --user=[username] --pass=[password]
