Add lua-hanging-indent-level.

[melisgl]

Examples with lua-hanging-indent-level and lua-indent-level being 4
and 2 respectively:

local foo = functionName(
varOne, varTwo, varThree, varFour)

local foo = functionName(varOne, varTwo,
varThree, varFour)

local foo = {
key1 = value1
key2 = value2
}

local foo = { longTableKey = value1
anotherTableKey = value3
}

something =
somethingElse

if foo then
doSomething
end

Any reason why this is not called lua-continuation-indent-level?

I used a different word because not all line continuations are
indented this way. In particular:

local foo = functionName(varOne, varTwo,
                         varThree, varFour)

Feel free to change it, if you prefer something else.
