[1.6.7][Clarity] weapon tinkers that require melee weapon

[slowclapman]

Razor Edge and Silver Filigree don't do anything when attached to a steamgun (crystal edge does however).
As far as I know, this works as intended but obviously I am not the judge of that.

However, there is no indication of this in-game so it would be useful to specify
this "melee weapons only" restriction in the create tinker menu and/or the description of the tinker itself.
