WebKit2 should load plugins from the same directories as old-WebKit

[Adam Roben (:aroben)]

Old WebKit (WebCore, really) has logic to load plugins from certain directories. WebKit2 should load plugins from those same directories.

Maybe we can return early if result != ERROR_SUCCESS?

I saw you used _countof in an earlier method.  Can it be used above also?

Ditto

Should we use ! instead of == 0?

Should we check the return value of PathCombine?

Ditto.

r=me too!
