Starting fails on Android 2.3 browser

[Felix E. Klee]

The game hangs while starting up when rotating the first board into place.

Console error log:

$ adb logcat browser:* *:S
--------- beginning of /dev/log/system
--------- beginning of /dev/log/main
V/browser ( 1688): use urldata
E/browser ( 1688): Console: Uncaught TypeError: Object #<an HTMLDocument> has no method 'contains' http://sq.rotogame.com/app.build/client/main.js:11

Fixed.

Steps:

• What is error message when accessing game in development mode?

  Console: Uncaught TypeError: Object #<an HTMLDocument> has no method 'contains' http://192.168.0.105:3000/app/client/hiscores_table.js:194
  

• Implement workaround for using unsupported document.contains().

• Bump version number to 1.19.2 in:

  • package.json
  • Git tag
