Fixed the path to load global shaders in the previous commit

* when DataLoadOrderPatch is disabled, the path was set to
"sfall.dat\shaders\".

 The graphics functions are only available if the user is using graphics mode 4 or 5. Use graphics_funcs_available to check; it returns 1 if you can use them or 0 if you can't. Calling graphics functions when graphics_funcs_available returns 0 will do nothing.
 
-load_shader takes a path relative to the data\shaders\ directory as an argument and returns a shader ID. That ID should be passed as the first argument to all other shader functions, and is valid until free_shader is called on the ID, the player loads a saved game or the player quits to the main menu.
+load_shader takes a path relative to the <GameRoot>\<master_patches>\shaders\ directory as an argument and returns a shader ID.

 get_shader_version gives you the highest shader version supported by the player's graphics cards. Possible return values are 11, 12, 13, 14, 20, 21 and 30.
