Change name of a tool when a brush is bound to it.

**Is your feature request related to a problem? Please describe.**
I am a heavy user of brushes and can often be using all 9 slots of my inventory for different brushes. I often run into the issue of forgetting which brush does what- especially after I go afk for a little while and come back.

**Describe the solution you'd like**
I think it would be nice to modify the brush command to accept a greedy string at the end. The greedy string would specify a name for the brush and then set the name of the item you bound the brush to the name specified. The command syntax would follow what I have below.

`/brush [name_to_set]`

So, if I were to create several clipboard brushes (each with a different object), I could have each of the brushes named accordingly.

**Describe alternatives you've considered**
An alternative I have considered is simply just renaming the item to the type of brush you're using. However, I think this would not be as intuitive, because if I were using multiple brushes of the same type, they would all be named the same.
