UplayLibrary was erroring when run without
Uplay installed. Needed to tweak it so that
DisplayMagician will work without Uplay
library or Steam library installed.
Changed to use natemcmaster's CommandLineUtils library to provide
flexbility for command structure, and enable the use of custom
validators which allow us to make sure that the command line options
provided are accurate. This removes the need for all the individual
exceptions being thrown across the main application.
Also started the modification of the CreateShortcut Form to make
it easier to use and more self explanatory.
And finally started the integration of Uplay into the application so
that users can use Uplay as well as Steam to select their games.
Migrated to the latest .Net Framework (v4.8) and changed to
System.CommandLine.DragonFruit for the parameter processing
as CommandLineParser completely altered their required
programme structure which meant something had to change.
Figured using Microsoft's own poduct would be best.
