Possible Figure Number error fix

- As described in Issue aimacode#80
- Figure numbers don't match textbook and `aima-python` codebase
- Figures 3.13, 3.16 & 3.17 needed be increased by one
- Figure 3.24 needed to be increased by two.
- New Figure Numbers are 3.14, 3.17, 3.18 and 3.26.
- Only needed to change README.md
