F2.registerPreLoadedApps should add classNames to root element (1.2-wip)

[colinStevenson]

When calling F2.registerPreLoadedApps - I would expect the appropriate F2-app classNames to be added to the root element.

@brianbaker , @markhealey - Feel free to assign this to me, if you can. I'll hopefully take care of this later today.

@Ali-Khatami, you're all set. Remember to keep your commit small (no compiled stuff in the wip). Thanks.

After some discussion around this, we've decided the Container Developer--not F2.js--should append the AppId as the classname on the outer-most HTML element when using preloaded apps. The end result should be similar to what F2 produces via the traditional method of loading apps as documented in the Namespacing part of the spec.

<div class="f2-app-container com_companyName_appName">
    ...
</div>
