Character reach indicator

Tool for showing your characters reachable range.

Adds a tool to your toolbar, when toggled on this will show 3 circles around your character.

Each circle indicate a different reachable range:

• _Reach distance:_ outer white circle, this is for most interactions with your factory. It defaults to a radius of __10__ tiles.
• _Resource reach distance:_ inner white circle, this is for interactions with environment, such as Rocks, Trees & Ore. It defaults to __2.7__ tiles.
• _Item pickup distance:_ small green filled circle, this is for picking up (default key _F_) items on the ground. It defaults to __1__ tile.

Interaction with entities

In Factorio every entity has a selection rectangle and a collision rectangle. The Collision rectangle is the one being used for determining if you can interact with the entity. As seen above, while the __selection rectangle__ of the tree is partially inside the character's _resource reach distance_ the whole of the __collision rectangle__ is outside, which means you can't reach the tree.

Collision rectangles can be shown using:

F4 -> show-collision-rectangle

Limitations: loot_pickup_distance, drop_item_distance & build_distance are not covered by this mod as in unmodded Factorio they have the same value as reach_distance.
