Images inlined for CSS inlines in HTML even when CssImageInlineMaxBytes is zero

[GoogleCodeExporter]

What steps will reproduce the problem?

1. Set CssImageInlineMaxBytes to zero.
2. Leave ImageInlineMaxBytes at the default of 2048.
3. Load a page that has inline CSS with images smaller than 2048 bytes.

What is the expected output? What do you see instead?

    The images should not inline, however, they do.

Please use labels and text to provide additional information.

The prioritize_critical_css needs to have image inlining applied consistently 
between CSS inlined in HTML and external CSS files.

Proposal: In inline CSS, only inline an image if it is smaller than both 
ImageInlineMaxBytes and CssImageInlineMaxBytes.

The planned fix will also update the documentation.
