Multireplace Sed

[justinnoah]

Thank you for improving Hamper!

Check one:

• [x] I remembered to bump the version
• [ ] This is a typo fix and no version bump is necessary

Does this fix an issue?

• [x] Fixes #51

Do you want this change to show up in the LUG hamper?

• [ ] I PR'd a version bump to LUG hamper
