- for all the plugins optimized the plugin name
- renamed the app to FlatCAM Evo in order to make a difference from FlatCAM app which follows its own path
- modified the splash image to reflect the new naming of the app
- modified some of the documents (License, Readme) in the app to reflect the actual reality in 2021
