[Bugfix] Several fixes (listed below)

- Fixed the error when trying to show the ToolTip of a hopperbin
- Also removed argument 'toolTip' of hideToolTip() since it's useless there
- Edited insertGear() a bit to not do weird stuff on phone (and weird code)
(Example of weird code: 'if(type(tostring(pos)) == "string") then' which is always true)
