Fixed SteamGame so it handles copies, and also
fixed the SteamLibrary so it works properly and
works. HeliosPlus now will run shortcuts and
load the game perfectly!
Pulled out the the library list mgmt from SteamGame
and put it in a new SteamLibrary class. This means I
can replicate the learnings from the ShortcutRepo
amd Profile Repo, and can save separate JSON files
in the future if I so desire.
There is a little bit outstanding to make the SteamGame
Properties to be writeable as well as readable, otherwise
the SteamGame.CopyTo function won't work.
Did a fix for the SHortcutAdaptor doing exceptions
for showing the form before loading all the graphics
but can't really do much about it without adding
background loading to the main form. This is a lot of
work considering we'll be moving from WinForms
to WPF UI in the future.
Also fixed the 'Do you want to save' prompt detection
logic so that it correctly waits until all the loading has
finished before monitoring for users making changes.
Should stop the form incorrectly suggesting you
should save unless they've really made a change.
