[modif] Patchwork Heroes (PSP)

In the game Patchwork Heroes (PSP), there is only one unique Time Trial group (instead of one per difficulty level). Based on the current submissions, the easiest is to:
- rename the Meilleur Temps - Easy group as Meilleur Temps / Time Trial.
- remove the groups Meilleur Temps - Normal, Meilleur Temps - Hard and Meilleur Temps - Pro.

The reason for the confusion is that the Scores menu is organized in four difficulty tabs, and below the top three scores in each difficulty level, the same top three times are repeated (compare the proofs here and there).

Thanks

Done !
