Add quotes around function keyword

[mrezentes]

Tests passing

@mrezentes version with no quotes is syntactically valid (in ES5+) and es5-ext is not meant to support ES3. Can you shed more light on why you need that?

I am running karma tests in browser stack. function is a keyword in Javascript. I don't think the word function cannot be used as a key in a key/value pair without quotes. This is the error that I am currently getting: IE 8.0.0 (Windows Vista 0.0.0) ERROR Expected identifier, string or number at /var/folders/7s/g48ds_0d09dgb28v7zb1c7mc0000gn/T/2e72f1fdd27e37aed14004c7345971d27664cf03.browserify:163:0 <- /Users/mrezentes/dev/paymentFrame.js/node_modules/es5-ext/object/is-object.js:3:0

@mrezentes it is not allowed in old ES3 (on which is IE8 is based), but technically both event-emitter and es5-ext won't run in ES3 environment, and not quoting function would be the minor reason for that.

I think you should either reconfigure tests to not run it in IE8, or if you make event-emitter somehow working in IE8 (through shims and shams), then you need to also apply fix like that one -> https://github.com/medikoo/es5-fix#es5-fixastreserved-identifiers-to-literals this will clear that issue for you

@medikoo Thanks for the info.
