Turns Response into a QObject and sets parent to the
command that emits it.
Each Command is also a child of the decorator commands,
Timeout and PageLoading commnds, so that deleting the
top level command will delete all the children.
See discussion in #430.
This prevents conversion of QByteArray to QString from truncating content at a null byte in the QByteArray. This truncation can be a problem if the response body is a binary object (e.g. PDF)
Fixes#322
specs pass with these changes (e.g. mainFrame() => currentFrame() and the new
injectJavascriptHelpers() code in WebPage.cpp).
It seems like the current JS+xpath implementation dives in to iframes already.
Is this desired behavior? I wonder if that works with x-domain iframes? I
doubt it...
Also, this design assumes that we only step one frame down at a time...
Lastly, I'm really not sure how QWebKit decides which frame is currentFrame().
For now, I'm hoping to be able to use the QWebFrame setFocus() method. This
may be a dead end though. We may have to have WebPage manually keep track of
the "current" frame.
