Update matchit to 0.8

Proposal

matchit version 0.8 was just released.

It includes changes to the syntax so now instead of /path/:arg/*wildcard it uses /path/{arg}/{*wildcard}. There are some other changes such as that now /path and /path/ are distinct.

All tests, examples, and documentation must be updated, otherwise the change is trivial.

This is a breaking change.

Do you want to work on this? It would be very appreciated :)

[mladedav]

Yeah, sure.

Can you please add the breaking change (and possibly other) labels and add this to the 0.8 milestone?
