add rerun()

[tyleretters]

started doing this in lua/lib/devtools.lua but that require()d too much effort on the dev side. scanning all the files already included this felt like the most logical place. open to feedback!

we have run into problems in the past single letter variables being overwritten or accidentally picked up in scripts so i’m hesitant to see the introduction of r

naming aside duplicating the implementation is not needed. functions are values just like anything else so r = rerun is all that is needed for creating aliases (which incidentally a user could easily do themselves)

fwiw stuff like this is also a great candidate for a mod

i'd be fine with

norns.rerun = function()
  norns.script.load(norns.state.script)
end

to facilitate less typing while staying inside the norns table, but i agree that we want to have fewer globals. also yes, this is a perfect candidate for a one-liner MOD.
