feat: no_implicit_parens support

[Iristyle]

• Support Coffeelint no_implicit_parens check by surfacing a config option (disabled by default), that will always insert parens around completion parameters, even when there is only 1 parameter and it is a function

BTW -- It would be a lot more convenient if these settings were tucked into some sort of config object. I expected to only have to tweak a few lines of code to read the setting from JSON, but ended up with a bit of a domino effect trying to get the setting from the point it was read to the point where it was being used.
