click on spider, first canvas attempt

I will probably redo the javascript and reimplement it with canvas, because I experience the first issues ...
Complete rewrite to canvas

The Game engine is completely rewritten to use canvas. There is a fallback that is not yet fully implemented using spans. It will probably be slow as all hell.

The map now moves around the player, and there are now more open things than before, but it stands on a better architecture.
Added gate again
Code cleanup
bugfix: move gates with player
move player per click
improved walkable check, open gate

Walk check is now 'graphically' detailed in gamedata.js with an ascii representation of where the player can walk.
Also the debug 'open gate' works again now.
removed wrong TODO
extended background
added spider (without attack)

Also some minor removings in background.tmx and index.html
