Random Modes and GUI

• Adds Random and LastHitPercentage shock modes
  • Random: Selects a random value between configured min and max values.
  • LastHitPercentage: Depends on how much health you had before the last hit, so getting one-shot leads to a shock 100% of your configured max_intensity.
• Adds a GUI to tweak the settings while the program is running, also now generates a config for you if you do not have one.
