GUI: Show user-provided names in grid widget

[orgads]

If the description is Some Game (DOS/English), then show the original title
(Some Game), since the DOS/English is expressed using icons. But in case it
has been changed by the user, show it as it is.

This won't work since not every game has (DOS/English) in the built-in description, and some games have ( in the title. That's why we stopped hacking around with (
The only clear way to fix this is to have a clear indicator of what is "user description" and what is "detection description" instead of trying to guess. For example we could default game entries to an empty description, which is filled in by the GUI, until the user customizes it.

I think the best approach here would be swapping game title and tooltip. E.g. show the user-provided name as default and game title in the tooltop.
