Title: Fix issue 1468: Better management of debugging #defines

Collect debugging #defines into a new single header file called config.h and wrap them with #ifndef's so that they can be set on the rake command-line -- e.g.:

```
CFLAGS="-DROXOR_VM_DEBUG -DROXOR_VM_DEBUG_CONST -DROXOR_COMPILER_DEBUG" rake
```
