I have made several small changes to margin-bottom-* tests.

1-
All these tests were declaring 'height: 0' but this was unneeded,
unnecessary. An empty block-level element will not generate a line box
[1]; so, 'height: auto' - which is the default - was good enough. So,
'height: 0' was simply removed.

[1]: "Line boxes are created as needed to hold inline-level content
within an inline formatting context. Line boxes that contain no text, no
preserved white space, no inline elements with non-zero margins,
padding, or borders, and no other in-flow content (such as images,
inline blocks or inline tables), and do not end with a preserved newline
must be treated as zero-height line boxes"

2-
0.2in was changed to 0.25in in tests margin-bottom-067,
margin-bottom-068 and margin-bottom-113 to avoid fraction of a pixel.

I have given this test (and margin-bottom-104) a lot of thinking and I
think this test is correct.
