Truffle/Instrumentation (part 2): For clients of Instrumentation, replace the TruffleEventListener interface with two: InstrumentListener, and ASTInstrumentListener. The former is simple, completely Truffle-safe (can't affect Truffle execution), and designed for simple tools. The latter is similar to the previous interface.
