Make Game over / Try again screen

[myselfhimself]

• Adapt from POC (screen-size..)
• Full-screen graphics (text & other)
• Auto-redirect to Home menu
• Game over screen (Arvo Pärt Tabula Rasa Silentium intro)
  Nice to have:
• Text is "Try again" instead of "Game over"
• Redirect to last level

Game over without Lives management is a bit too difficult -> replace "Game over" text by "Try again" instead.
Requires last level variable passing into anchor from level.html to level_intro.html (game over screen)...
