Modified CSS to make game board smaller

- Reduced size to 710px
- Renamed old css as homepage_large for possible use later
Functions fix (again)

Moved priority statement to correct function.
Home page template

Shifted code for game board to the home template not the content area.
Responsive CSS

- Use 960 board for windows big enough to see the whole board at once
- Use 710 board otherwise
- Fixed IDs in homepage_large
- Altered head tag in template to import correct css file
