Allow bulk remap

[six7]

If users needed to rename a large portion of their tokens and they already applied these tokens before, they currently have a hard time trying to remap all of that.

Often times, this could mean that a user changed the name of a root group to something else.

We should add a button to Inspect that opens a modal that lets the user remap lots of tokens:

This modal should have contents of

• Match [INPUT, optional]
• Remap to [INPUT, required]

Having an automated way that

• takes all layers where the tokens were applied
• finds %MATCH
• replaces %MATCH with %REMAPTO
