[Opa] Json type in javascript plugin

[Matthieu Guffroy]

After reading a little bit more the documentation I think this function
will be more usefull than the previous :

Json.to_string_in_js :
RPC.Json.json<http://doc.opalang.org/api/stdlib.core.rpc.core.json.opa.html#type_stdlib.core.rpc.core.RPC.Json.json>
 → string

I think to_string is only for rendering a string and to_string_in_js is a
string readable by js code....
