SearchWorldEnhance

This is a lightweight mod run on client-side, which brings a “Search World” box to world selection screens(prior MC 1.13) and enhance the searching behaviour by using key-value pair arguments.

This mod adds a “Search World” box to the world select screen(prior MC 1.13), and the searching behaviour is now like this: `worlddirname-=foo` - Search for worlds whose directory names contain `foo`, case-sensitive `worldname/="^New World$"` - Search for worlds whose names exactly are `New World`, case-insensitive `gamemode=S,commands=true` - Search for worlds whose default game modes are Survival and commands are enabled
