This works through a new field "touch_interaction" in item definitions.
The two most important use cases are:
- Punching players/entities with short tap instead of long tap (enabled by default)
- Making items usable that require holding the place button (e.g. bows and shields in MC-like games)
Don't place nodes when closing button bars.
Update docs (also in-game).
Rename "Default controls" -> "Controls" in Android pause menu since players can't change them (normally), so calling them "default" doesn't make sense.
