First-open Window & new version window #37
Description
The first time that the application is run it should display a "welcome" 👋 screen. The screen will give links to the documentation pages, links to the getting started page, and warn that the TM1638 library must be installed if using those displays. This screen will stop displaying when there is a valid current.opt file in the directory. The current.opt will store the current selected configuration, the last version of the application used. If the last version used is different to the current version then show the "What's New!!" window. 🆕
