Suffix support?

[hakunin]

Hi, it would be nice if there was a global suffix support.

This is how I imagine it could work API-wise:

Root level, producing MyApp.

<DocumentTitle title="null" suffix="MyApp" separator=" | ">
 ...
</DocumentTitle>

Inside a specific page, producing Index | MyApp.

<DocumentTitle title="null" suffix="MyApp" separator=" | ">
   <DocumentTitle title="Index">...<DocumentTitle>
</DocumentTitle>

There could be also custom format function for those who need more power:

<DocumentTitle title="null" format={(value) => value ? value+' | MyApp' : 'MyApp'}>
   ...
</DocumentTitle>

A similar proposal was mentioned in #6 with a potential solution (wrapping the component)

@hakunin I had same use-case so I've created similar library that supports that API: react-titled

It was hard to add support for it here since react-document-title has fundamentally different implementation (not using context).
