Feature Request: Search and replace for compound tags

[iosefward]

I've got a world that used to have a mod on. It's left a compound tag in every chunk that stops the world saving. I'm currently having to search manually, one at a time, and delete the compound tag.

Would it be possible to add a way to search and replace compound tags?

This could well be closely related to issue 97 too.

I need this too, my whole world is corrupted and I'm not doing 70k chunks by hand
