Add the option for potion effects while holding a tool

[Former user]

Consider adding in the option to induce one or more potion effects on the player when they're holding a tool. This is another thing that Tinker's Construct does that would be very helpful in creating unique tools and weapons.

If added, please include an option to determine the level of the potion effect, and if there should be a "lingering effect". (With maybe the time given for the effect more than 0:00/0:01 (which should be just for holding the tool)))
