We would like to enable access to local storage from Web Inspector. However, there are two problems:

1. privateBrowsingEnabled setting is true for web inspector pages (see WebInspectorClient.mm), this prevents web inspector from modifying local storage (see StorageAreaImpl::setItem). According to comment, this is done to keep inspector out of history.
This can be solved by introducing new setting "excludeFromHistory" and then using it instead of "privateBrowsingEnabled" in WebInspectorClient.

2. chrome registers "chrome:" schema as no access (see RenderThread::EnsureWebKitInitialized), this prevents web inspector from accessing the local storage.
We can add "allowLocalStorageAccess" setting like it's already done for "allowUniversalAccessFromFileURLs" (see Document::initSecurityContext). But I don't feel like it's a good solution.

Any thoughts?
