Dialogue System Improvements

I've taken some free time before implementing new poses and body customizations to make some small improvement changes to the dialogue system, but which they add a lot to the reader experience:

• Text background changes according to the character theme color

• Added text color highlight

• Text Hint: now all dialogues that are a consequence of your choice will have an underscore markup. When you hover your mouse on this text, it'll show which dialogue option causes this choice

• Showing the next dialogue now works with any keyboard key, or mouse button
