New feature: Info popup component

[Wiiolis]

Description

New feature that's allowing to add info button on cards with popup and description.
Fixed #issue
It extends Generic component.
Data format is:

item: {
  info: {
    header: "fancy header",
    content: "fancier content"
  }
}

I'm pretty new to all this forking stuff so if you don't like it that's fine. I just wanted to try it and maybe contribute with something useful :D
