add editor button to force reload the current module

[ngwese]

when developing a (lua) module changes don't get picked up if the module has been already been loaded via require.

it is possible to force a module to get reloaded by setting package.loaded.<module_name> = nil then calling require '<module_name>'

to facilitate module development it might be nice to have button in the editor which sends this to the repl (after a save), or by making the save button more smart...

following up on a conversation on lines, as @catfact pointed out elsewhere a work-around is to explicitly un-load the module (to the extent that you can).

the basic idea can be expressed in a helper function, like this:

function reload(module_name)
  if (package.loaded[module_name] ~= nil) then
    package.loaded[module_name] = nil
    _G[module_name] = nil
  end
  return require(module_name)
end

that you use in your script like this:

-- reload, really.
local foo = reload("foo")

in the simplest cases this works well enough during development.

(FWIW: i put this function in a utility library that i use while writing scripts; works great.)

this is largely no longer an issue now that include(...) is a thing
