// ModifyTokenImage v1.0.5
// By: Zachare Sylvestre
// Concept was based on ChangeTokenImage but utilizes the Handout Repository, which allows for a little more robust look for tokens.
//
// Version History:
// 1.0.4: Refactoring the GMNotes so that it works a little better with different JSON Objects that might want to use the same item.
// 1.0.5: Adding optional token size parameters to the handout gmnotes.
