What will change with this Pull Request?

The startup routine has been simplified, removing a lot of blocking steps when running a fresh installed or a just updated installation:

• detect if this is a fresh installation or an update, and show a different welcome dialog informing the user to run oracle; eg. for new install:
  
• don't show tips window on first run: having a both a modal welcome dialog and a the tip window coming up at the same time is just too confusing; tip window will only show up on subsequent runs;
• Tip window: ensure it's raised on top of the main window;
• remove the "Update completed successfully. Cockatrice will now reload the card database." popup dialog; it's just redundant and you can't avoid it;
• Remove the "The sets database has been saved successfully." popup when saving the sets dialog: it's redundant to inform the user of something that's expected to happen when confirming a dialog;
• Remove the "The card database has been saved successfully to ..." popups in oracle. Instead, show the default path on the wizard page. Also, invert the "choose custom path" checkbox logic to make it more user-friendly:
  

I made some tests on fresh install / update / subsquent installs, but I'd really like some external testing on this. Thank you

First quick check

Thanks for the path fixes, they are displayed correctly now. 👍

I have three further suggestions though:

• It now simply closes automatically without a hint or comment after the token step. The user can't be sure if everything went well, something crashed or whatever. Maybe he realizes a reload, sometimes there might be a new set popup...
  But I think we can be more clear and helpful here. Especially for very new users.
  
  There could be a very last, new conclusion page in Oracle that gives you an overview of what happened so far, which steps succeeded, where files are stored and that the database update process is finished for example. Also giving the user the hint that Cockatrice will automatically reload, and that the user should restart the client if something isn't working as expected.

• Can you reorder the phrasing with the paths a bit? I think that is more expressive:
  

• The token import has two steps. Since it's only a simple file download, no parsing and processing it could all simply be on one single page: (token source selection + tokens imported)

Added.

Done

Done for both tokens and spoilers.
