Applied some balancing fixes based on demo for feedback (especially related to special cards’ effects)

Added the “coin toss” animation and a new popup to display stat change outcomes, including a particle animation. A couple of changes to spice up the game a little bit.

Integrated a new pack of UI assets which included thin borders for popups, and stronger outlines for buttons. I got a lot of colors options from the artist, and didn’t know which one to use. So I used my bad programmer’s judgement.

Finally, fixed some event outcome texts that were wrongly displaying redundant outdated text for the actual effects on the stats.
