Sparks Hammers

- Removed redundant localisations from en_US lang file

- Repair material for tools is now set based on the dependant item set in the customTools.json file

- Added a LocalisedName property for tools in the customTools.json file

You will probably find due to some changes I made that your tools won't show up in-game. Delete the customTools.json file in the configs directory and let it auto-generate. If you have edited your file, the you may want to move the file instead and edit back in your changes after.
