TypeError: Cannot read property '1' of null at parse call

[okv]

Hi, there!
I have following error when try to parse user agent:

TypeError: Cannot read property '1' of null
    at Object.parse (node_modules/platform/platform.js:783:54)

My user agent is "todotogo/6 (iPhone Simulator; iOS 6.0; Scale/1.00)".
This user agent is auto generated by AFNetworking (https://github.com/AFNetworking/AFNetworking) library.

It would be great if platform.parse method just return null or undefined if he can't parse browser name, version, etc.

If a check for layout is added to line 796

    // detect Chrome desktop mode
    else if (layout && name == 'Safari' && /Chrome/.exec(layout[1])) {

todotogo is detected as a generic Safari on iPhone.

{
  "version": null,
  "name": "Safari",
  "os": {
    "architecture": 32,
    "family": "iOS",
    "version": null
  },
  "description": "Safari on Apple iPhone Simulator",
  "layout": null,
  "manufacturer": "Apple",
  "prerelease": null,
  "product": "iPhone Simulator",
  "ua": "todotogo/6 (iPhone Simulator; iOS 6.0; Scale/1.00)"
} 

Not perfect, but far better than throwing an exception.

We are using the current version of Platform (1.0.0) -- though I just realised that that doesn't include the code update 3 months ago, probably because the version number wasn't increased -- to determine the CSP headers supported by the client's browser. In rare cases platform.js causes this exception on line 796 because layout is set to null in line 258.

We didn't log the user agent string that caused this issue but an unknown user agent should certainly not lead to a crash. @terinjokes suggestion would solve this particular crash but layout is assumed to be an array in other places too.
