Add split and join macros
Created originally on Bitbucket by prof_yaffle
It'd be useful to have macros which can split a string up into an array and join an array into a string rather than needing to use javascript.
#!
(split: "1:2:3:4", ":") rather than "1:2:3:4".split(":")
(join: (a: 1,2,3,4), "-") rather than (a:1,2,3,4).join("-")
I have implemented versions of these macros and can send a pull request if required.
