Title: Add explicit numeric constant value for all opcodes

- Easier for debugging (what opcode was 0x... again?)
- Clarifies that the opcodes are set in stone in the protocol, and signals that it is impossible to insert opcodes in between.

I've checked that the old and new representation are exactly the same, see http://pastebin.com/dnsyyfFD for testcase. This needs careful scrutiny though.
