I've also added some support for compiler errors in general, but these will get expanded on later. I've also quickly added a valgrind option to the tests and found a few leaks. I'll deal with these later. Summary of changes: * Clarified the lifetime of the bytecode in memory * Erroneous routines exit without compiling * Empty VMs don't run * Added a check for malformed assignments * Renamed "routine" to "module" within the VM * VM no longer tries to free the bytecode - must be done manually * Started experimenting with valgrind, not yet ready
