When looking up the history of a specific player in a roster there's one dropdown with all (500+) players. Being able to search or filter would be lovely.

This should add search to:
Profiles GUI
Standings GUI

Search should be done by name
probably with smth like string.match(name, ".*searchname.*)
This search should be implemented as filter, functioning instead of class checkbox (when search is going on then we disregard the checkboxes)
