squirrel script - bug select tool by key function is_work_allowed_here()

[Andarix]

The idea is correct, but the value is wrong.

The `tool_id` is correct. Only the object name is passed differently.

The name is passed via the button.
The value 1 is passed via the key "s".




Docu function
is_work_allowed_here()

The description doesn't seem to be entirely correct either. There, "name" is defined as "coord3d".

I think this is a simutrans bug, not a tutorial bug.
