Compact Conflict - modifications for this site

Commit:   772f4a0309c2a41b3360d0dd48b5e235fbb98658
Author:   Jakub Wasilewski (zlib license, see LICENSE - unchanged)

This is an altered version of the original software. Changes:
1. Renamed the script file erisk.js to game.js and updated the <script> tag in index.html.
2. index.html: the author credit on the title screen is kept, but the external link
   to the author's website (http://wasyl.eu) was turned into plain text so the game
   frame cannot navigate away.
3. game.js, playSound(): resume the Web Audio context if the browser created it in a
   suspended state, so sound effects work after the first click. Sounds still only
   play in response to player actions.
4. Only index.html, the script and LICENSE are shipped; build scripts, IDE files and
   README were left out.
No gameplay logic was changed.
