Luacheck and Selene

[ShalokShalom]

Selene is a modern, maintained linter

Is there any chance, we use that one, instead of luacheck?

Since this plugin supports loading each linter individually you could send a PR adding a separate selene linter here https://github.com/liquidev/lintplus/tree/master/linters
