Settings form isn't used which causes imageapi_jpeg_quality to be ignored.

The imageapi_gd module has a settings form that is never displayed. When setting the jpeg quality it's the form generated by image_gd_settings() (in includes/image.gd.inc) that is displayed. This saves the jpeg quality level in image_jpeg_quality. Since the variable imageapi_jpeq_quality is never saved the default value is always used when saving an image.

I've removed the references to the imageapi_jpeq_quality variable and now use image_jpeg_quality.
