allow table fields assigned to local functions to show as functions

[hahn-kev]

Example:

local function otherVal(test)
    return 1
end


local MyClass = {
    aFunction = function(self, param1)
        return 's'
    end,
    bfunction = otherVal,
}

local t = MyClass.<??>

if you do autocomplete at <??> you will normally get these results:

• aFunction(self, param1) with a function icon
• bfunction as just a simple field icon

this changes that so that bFunction shows up in autocomplete as a function too. In this case it would show up looking like this bFunction(test)
