REPL QoL

• Add 'classEnts' (ents.FindByClass)
• Add fuzzyThat (FindInRadius for there)
• Add closest"entName" FindInRadius->filter->sort->limit 1
• Add proper formatting of serverside vector/table stuff
  • Functions should append short_src/line
• (maybe) lambda syntax
  • opt 1: |arg| "implict return", |arg| do local this="isblock" return this end
  • opt 2: (arg) => "nice"
  • ext 1: implicit ::propertyAccess lambda, ::AlsoCall(withArgs)
• (maybe) pipe filters, eg. classEnts"myent" | filter .flag == true
  • also pipe mutators classEnts"myent" | each :DrawShadow(false)
  • lambda syntax could probably replace pipe -> each(classEnts"myEnt", ::DrawShadow(false))
