Renaming a block should update old references

[charlespwd]

Is your feature request related to a problem? Please describe.
When a block/*.liquid file is renamed, references to it should be updated to the new name

Describe the solution you'd like
When a block/*.liquid file is renamed, references to it should be renamed:

• In block presets?

• In section presets?

• In sections/*.json files

• In templates/*.json files

• {% content_for "block", type: 'oldName' %}

• if a block becomes private and it was previously included by @theme, a { type: "_newName"} should be appended to the list of block definitions. EDIT not doing this one. Too much work and would cause a lot of toil.
