[Feature Suggestion (?)] Tap-Run vs Hold-Run option

[JadeJuno]

I've noticed that, unlike the official PMD games, to run constantly through a hallway until a real interruption (i.e. a wall, another pokémon or a crossroad) you have to hold that direction, instead of just being able to tap Run+that direction like in the official games.

I suggest adding an option to change the running method in the Settings menu.
This was already suggested on #174 together with a bunch of other control revamp ideas, but since it's been 2 years and it has gotten no answer I thought it'd be a good idea to bring it up again.
