New features in Randomizer

Randomizer.GenerateConditionalJumpInstruction(...) now accepts both
NoOperation and UnconditionalJump statement types for processing.
Andris! Please delete MakeFakeInstructions.cs ->
ConvertUncondToCondJump(...) method, and use
Randomizer.GenerateConditionalJumpInstruction(...) or
Instruction.MakeConditionalJump instead.
