Homepage Updates

- Homepage: Added category images for the follow categories: chess sets:
garden and travel chess sets. Chess boards: natural wood chess boards.
Chess accessories: chess clocks, books, dvds, and software.
- Homepage: Updated Category boxes with the following changes:
Vertically centered category title text. Reduced whitespace between
category rows. Upgraded title bar font size to 14px.  Relocated the next
and prev category scroll buttons to be positioned correctly with the new
category dimensions. Resizing of the title bars would throw off the
whole look of each category as there is a border that surrounds the
entire item. This border would contain uneven white space in between it
and the title bar if it were to be shortened.
