#4 Add handholds_redo support

    ...

        pick_axe_tweaks.register_pick_axes({mod..":pick_"..name})

https://content.minetest.net/packages/TestificateMods/handholds_redo/ Much like #3 adds support for this mod if it exsists. One note though: this PR might conflict with #3. If it does, be sure to register this one after pickaxe tweaks. I'll be keeping an eye out to make sure that when you do merge a PR I might be able to make these minor conflicts even easier to deal with. Here's what that would look like: ``` ... if minetest.get_modpath("pick_axe_tweaks") then pick_axe_tweaks.register_pick_axes({mod..":pick_"..name}) end if minetest.get_modpath("handholds_redo") then handholds.register_pick(mod..":pick_"..name,level) end ... ```
