Inverse swipes option for Android devices

# Is your feature request related to a problem? Please describe.

Add an option in the android menu that would allow a swipe in one direction to move the character/menu/navigation in the opposite direction of the swipe. That way a swipe left would move the character right (giving the impression the user grabbed the terrain and moved it under the character)

# Describe the solution you'd like

An optional 'inverse swipes' false/true could solve this.

# Additional context

Player has tried to change the key bindings but I didn't not manage to inverse the diagonals by assigning NE or SW to their opposite swipes, for example.

Feature request came from one players via email.

The issue points to the Android menu, swipe handling, and key-binding behavior; begin by tracing those entry points and how cardinal and diagonal directions are mapped. Done means an optional inverse-swipes setting reverses swipe movement without changing the default behavior, with the setting exposed in the Android menu.
