[Docs] issue with left navigation (inline-styles-prefixer)

[divinetouch]

I just forked the project today and tried to run the doc site on my local but keep getting error when trying to open the left navigation.

The error was thrown by the inline-style-prefixer library with the message Cannot read property 'indexOf' of null. Because I'm really new to this Material-UI project I don't know whether Material-UI fails to properly call the inline-style-prefixer APIs or inline-style-prefixer fails to properly check to make sure all the required params as not null or undefined.

There are two places that inline-styles-prefixer throw this error, flexboxIE.js and flexboxOld.js.

flexboxIE.js

if ((properties[property] || property === 'display' && value.indexOf('flex') > -1) && (browser === 'ie_mob' || browser === 'ie') && version == 10) {

flexboxOld.js

if ((properties[property] || property === 'display' && value.indexOf('flex') > -1) && (browser === 'firefox' && version < 22 || browser === 'chrome' && version < 21 || (browser === 'safari' || browser === 'ios_saf') && version <= 6.1 || browser === 'android' && version < 4.4 || browser === 'and_uc')) {

In both cases the error occurs when the property is _display_ but the value is _null_

To get rid of the error temporary and allow me to run the doc on my local I added the check for value : typeof value === 'string'.

Please let me know if this is purely inline-style-prefixer bug and I should open an issue with them instead.

versions

-Material-UI: 0.15.0-alpha.1

That should be fixed by robinweser/inline-style-prefixer#71.
