Find/replace strings in the properties table

[tmcw]

One of the many properties-table enhancements: it'd be nice to find & replace in the properties table: if you have lots of properties with some common mispelling, unifying NA and N/A for example, a traditional find/replace UI could be nifty.

I think this is mainly a UI/UX challenge: find & replace across properties is pretty simple to implement, but where to put this UI, and whether to support previewing or other more complex UIs is up to the implementer to decide.
