New step status indicator on messages and better testing UI

v1.2

Update README.md

Added options and color variables

You can now change the color of the background and the message field as well as you're now able to control weather the intro is canceled by clicking on the background.

Version 1 - Stable

The whole library is stable and intuitive to use, so I release and leave it as it is for now.

There are some tiny issues:

• resizing doesn't work well in some corner cases
• animations would be good, but Xojo doesn't provide some thing like that out of the box

Contributions welcome!
