Make sorted serialization faster

Browse source 
Redbean Lua and JSON serialization now goes faster because we're now
inserting object entries into tree data structure rather than making
an array and sorting it at the end. For example, when serializing an
object with 10,000 entries this goes twice as fast. However it still
goes slower than saying EncodeJson(x, {sorted=false}).
