Rename Matches to Match.

[XAMPPRocky]

Match could be a better name for the filter? think I remember a while ago @markmandel and I had discussed having a convention for filters and to use verbs like compress/encrypt where possible (not sure how well we've kept to it ^^)

I think Match would be better -does seem to be inline. We should probably document the standards for Filter names somewhere as well.

Did a quick playground test, and Rust doesn't complain about a struct called Match
