To have a faster autoloading. We should get rid of those of course. But
for now I do not see it happening any time soon.

We can't use an authoritive classmap in the current state as it would
kill app loading. However we can use a proper classmap for the normal
core stuff.
This introduces the defacto standard PSR-4 autoloader from composer into
core. This will allow proper PSR-4 naming of our classes.
Since our original autoloader is still available we can slowly switch
over classes to PSR-4.
