- downgraded to 1.3 - some examples in 1.4 are empty (see:
http://sources.redhat.com/autobook/autobook/autobook_59.html#SEC59
http://sources.redhat.com/autobook/autobook/autobook_60.html#SEC60
- ver. 1.4 was never released, so I didn't bump epoch
- changed examples background color for better readability (both bg & text
were dark)
