Truffle/Instrumentation: rename the most recently created kind of Instrument, formerly "ToolNodeblahblah...". It is now defined by SpliceInstrumentListener. This listener allows the client to create an instrument that will *splied* a client-supplied AST fragment directly into a Probe's "instrumentation chain", and this directly into the flow of Truffle execution (with full optimization).
