Sourcecode is visible for every file even when runtime option --sourcecode is not used

[mbed67]

According to the documentation http://www.phpdoc.org/docs/latest/references/commands/project_run.html#description
and
http://www.phpdoc.org/docs/latest/references/phpdoc/tags/filesource.html
the tag @filesource should create a link to the highlighted sourcecode of that specific file and the runtime option --sourcecode should do this for every file.

This template creates links to view the sourcecode for every file, even though --sourcecode is not used.

A file that has the @filesource tag is phpDocumentor\Tests\ReferenceImplementation.php

In the documentation for this file there is a label "filesource", but it doesn't do anything.
