Removed unused method
Added generic extract- and implantBindings methods for all StormReteBolts
Properly combined old ReteTerminal Bolts with StormReteBolt behaviour:

Original StormReteTerminalBolt: just uses tuple as binding environment, both in and out

Original ReteTerminalBolt: just uses binding environment as value in tuple, both in and out

Needed by ReteConflictSetBolt: binding environment as value in tuple for input

Delivered by StormReteBolts: tuple as binding environment as output

New StormReteTerminalBolt: tuple as binding environment in, binding environment as tuple out.
