Tim-specific code

[dylanevl]

To get this to run, I had to change line 14 of server.js to:

var world = worldDB(__dirname + '/node_modules/world-db/data/world.db', 1024, 10000);

I also created an empty 'world.db' file in /node_modules/world/db/data to avoid the next error.

There is also a reference to /tim/ in tiles.svg on line 19.
