add SVG.py

Issue

• fix Request - SVG image rendering #22

Content

• Added ./shogi/SVG.py.
• Updated ./shogi/__init__.py to append board.svg() method.
• Updated README.rst to introduce board.svg() method.

How To Check

• I cant understand how to write and run test in this project.
• So I've checked my code by python interpreter.
• $ python
• >>> import shogi
• >>> board = shogi.Board()
• >>> board.svg() should output SVG text.

Others

• Base SVG string is published under Creative Commons BY-SA License, Is it safe to merge?
• If there are coding rules in this project, let me know so I can follow them.

@yuiseki
I generate a SVG file like following, but the image only contains a shogi board, not komas.
I checked with Firefox and Adobe Illustrator.
Could you check that?

import shogi
board = shogi.Board()
print(board.svg())

I pulled yuiseki's branch and didn't have the same problem as you (pieces were loading! - not all though). I forked the project and managed to get it to work

Default Board (as in your example)

SFEN ('4+R3l/1r1+P2gk1/3p1p1s1/2pg3pp/1p4p2/SP4PPP/2NP1PKS1/2G2+n3/8L w B2N2L3Pbgsp 10')

I can open a new pull request if you like to see!
