Searching Categories should filter

[bpaulien]

I have a category called "Transportation Fuel" (don't ask me why, should just be "fuel") But if I type "fuel" when searching for categories, it won't find it, it goes to "Flea Medicine" (first category it finds starting with "F".)

Another thing I'd like is if I have a category called "Clothing - Kids", and another one called "Kids Activities", I'd like the search to filter down to show both of those categories when I type "Kids".

The fuzzy matching desired in #432 would be great for this need.

Probably also same as #639

Yes, this will be fixed with #432 (edit: should have said #153), so I'll close this one as a duplicate.
