Optimized performance of the debug build.

The shopping example took about 3.8 seconds for the initial rendering due to garbe collection and
allocation of our inlined '__DEBUG_METHOD' object.
I speed it up at cost of more runtime memory (in the debug build) with
moving all the inline definitions to blocks.debug.methods object.
Every function now gets a unique id (just counting up).
Now it's arround 1.5 seconds.
