gtalbot /text-align-007 to 013 need correction

I have been review and updating test cases this week. Here are a collection of cases that need some correction.

Test cases involved are:
http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-007.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-008.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-009.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-010.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-011.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-012.htm
                http://www.w3.org/Style/CSS/Test/CSS2.1/20100127/html4/text-align-013.htm

Each one of these test cases assume that text-align will be inherited by default into the 'th' element. However the 'th' element has an explicit default style specified on it of 'text-align: center' which would prevent the default inheritance from occurring.

These need simple pass condition updates. Something along these lines I think would be satisfactory:

Test passes if the words "Filler text" are horizontally centered inside the rectangle with a thin blue border.
