Adding phpdoc.php to execution path does not work

[pgraham]

Steps to reproduce (Unix):

1. clone phpdoctor somewhere on your maching.
2. cd /path/to/phpdoctor
3. chmod +x phpdoc.php
4. Add phpdoc.php to the environment path variable
   (I have a private bin directory from which I've created a symlink to /path/to/phpdoc.php
5. cd /path/to/project
6. Execute: phpdoc.php phpdoc.ini

Expected results:
phpdoctor should run

Actual results:

The following error is encountered:

PHP Warning:  require(classes/doc.php): failed to open stream: No such file or directory in /home/pgraham/projects/phpdoctor/classes/phpDoctor.php on line 40
PHP Fatal error:  require(): Failed opening required 'classes/doc.php' (include_path='.:/usr/share/php:/usr/share/pear:/home/pgraham/bin') in /home/pgraham/projects/phpdoctor/classes/phpDoctor.php on line 40

Patch:

The fix is pretty simple so I've included the diff here but if you prefer I can fork and make a Pull Request.
