Prevent Infinite Loop in ShowActionSequence

Addressing issues with infinite looping when showing an action sequence

InputOutput:
- Changed the way step amounts are assigned in the inspector to be more
intuitive
- Created Start method to assign the step amounts correctly.
- Debug entries to exhibit problem with action objects added
- Used == instead of .Equals (avoiding infinite loop when performing an
action)

Game.unity:
- Assigned step amount and multiplier in editor (Slightly sped up unit
movement)
