DISCLAIMER: I used GitHub Copilot to help implement this feature. If this is not allowed or not wanted, please close this PR without merging and I will rewrite the logic myself and re-submit at a later date.

This PR implements the enhancement request in #1029.

Features implemented:

• Toggle preference for "Icons bounce when launching?" (Needs localization)
• When enabled, upon clicking an application icon that has no launched windows, the icon will bounce a minimum of 1 time and a maximum of 5 times. If it is able to detect the application target is RUNNING, it will ease out the bounce back to the original location and will not perform another bounce.
• When disabled, the icons do not bounce.
