Performance optimization

[bennobuilder]

How did we optimize the performance?

1. optimizing the bucket functionality of the runtime
2. optimizing the logging behavior
3. removing defineConfig
   The disadvantage of removing defineConfig, is that now default values aren't applied to undefined set properties.

   // Now the default property of 'background' 
   // can't be applied to the configuration object because it is set.
   MY_STATE.set('jeff', {background: undefined}); 
   

   Will be fixed in Default configurations aren't applied to undefined set properties in a configuration object #173
4. small optimizations like replacing forEach loops with for loops, ..
