InputMap already has action "left_mouse_button"

[arnaudgolfouse]

This is really a small nitpick: when launching the main scene (visualisation.tscn), godot complains:

E 0:00:00.705   add_action: InputMap already has action "left_mouse_button".
  <C++ Error>   Condition "input_map.has(p_action)" is true.
  <C++ Source>  core/input_map.cpp:89 @ add_action()
  <Stack Trace> gridmap.gd:14 @ _ready()

With my limited godot knowledge, I think this happen because we define "left_mouse_button" twice:

• Once, as the error says, in gridmap.gd, line 14;
• And also in the project's settings, in the InputMap panel.

Removing either one fixes the message (and all scenes keep working), I just don't know which one should be kept.
