Goaded by some coworkers about the opcode searching functionality of windbg prompted me to add a new option to jutsu today: searchOpcode

You can search for sets of instructions in conjunction, it will assemble them, providing you the machine code, then search for the instructions in executable memory. Instructions are delimited by pipes. I plan to add some limited wildcard functionality in the near future as well.
