[Feature Request] Fuzzy matching as a fallback

[0xC0FFEE]

One feature I really liked in fasd is, that fuzzy matching is performed, when the other matching algorithms to not yield a result.

Comparison of matching algorithms in fasd and z.lua:

fasd

1. Queries match the path in order (same as default method).
2. The last query matches the last segment of the path.
3. If no match is found, fasd will try the same process ignoring case. If still no match is found, fasd will allow extra characters to be placed between query characters for fuzzy matching.

z.lua

1. Queries match the path in order (same as default method).
2. The last query matches the last segment of the path.

Did you consider to make the 3rd matching algorithm available in z.lua?
