#10011: Use of add_theme_page() causes Wordpress on IIS to crash.

 The P2 Theme uses the following line to add a theme settings page:
 add_theme_page('Prologue Options', 'Prologue Options', 8, __FILE__,

 On IIS this causes a 500 Error and the admin section can not be loaded

 When we substitute `__FILE__` by a string, e.g. "p2" everything starts
 behaving again.

 The following might be the cause of the problem:

 `__FILE__` is passed through the function `plugin_basename()` in
 `add_submenu_page()`... usually that function strips out the path and
 returns only the plugin filename; for themes that does not work and the
 function returns the full path to the theme's `functions.php`.

 I don't know why it only crashes on IIS but the value of
 `plugin_basename()` is used for a few things including for registering an
 action hook (which means that it's probably used as a key of an array at
 some point).
