Dmitry Tantsur c5b99058b2 Flatten the emulator resources
It doesn't look like we'll get more alternative implementations for
all resources except for systems, nor do we allow loading 3rd party
ones. For the sake of simpler development, flatten the package
structure and get rid of most abstract classes.
