Previously, sort, reverse list, and join functionality was implemented
as special cases in Bonsai itself. Given that it has usecases
(especially in material lists, but any sort of list applies) I've moved
this function into the IOS formatting language.
The IOS formatting language previously wasn't capable of this, but the
awesome addition by @falken10vdl made the formatting language accept
queries inline, so that means it can handle lists. I also added tests
for all the new functions and expression syntax (+-*/ operators).
I simplified the code that gets the evaluated text literal - previously
it seems to call format() multiple times.
