Feature request: autocompletion for property names that are not identifiers (e.g. "font-family")

[duanyao]

Currently TS tools can't autocomplete property names that are not identifiers. e.g.:

interface Style {
    'font-family'?: string;
}

There is no autocomplete for the following input:

var style: Style = { 'fo // no autocomplete
style[ // no autocomplete
style. // no autocomplete

I think maybe TS can do better here: show a list of all properties, after user has selected one, quote it and use brackets if neccesary.

hey @duanyao, thanks for filing. I think this is a duplicate of #606.
