Request: reminder management via search and tag-renaming

[wolftune]

Workaround is feasible by exporting the JSON editing and re-importing.

Would be nice though if I could search the reminders and if I could rename a tag without changing which reminders have it

P.S. I am loving this still, and I hope to sometime share an export of my reminders for others to draw from

For tag renaming: another user requested the ability to bulk disable/enable via tag. I could see having the ability to rename a tag based on this same UI as well.

Search would be nice. I'd have to think about how to implement all of this though, in terms of keeping the UI simple.

Tag renaming to be implemented under #44
