Make JSZip act as a library for QML
Add qhttpserver to project

This includes some small modifications for it to work with QML.  The app
is modified to give a listing of the Epub file's contents.  Text files
are returned correctly, but binary files are not.
Pass base64 encoded data from JSZip to server

This is pretty silly, but there doesn't seem to be anything in QML that
represents a string of bytes.  Qt has QByteArray, but that doesn't seem
to be exposed to QML.
Add Monocle

Now we can actually view Epubs!
Improvements to the WebView

We set the viewport to ensure the view takes up the whole width, and we
disable scaling on double tap.  This seems to make the title go away in
the webviewpage, although I'm not sure.  Setting flickable: null may
help out, though it's not necessary and is commented right now.
Improvements to Monocle reader

The PlaceSaver saves the position in the book, even across invocations.
The stencil makes clicking on internal links work.
Handle external links

Monocle gives these links target="_blank", but WebKit doesn't give us
any way to see that happening.  See
https://bugs.webkit.org/show_bug.cgi?id=91779 and
https://bugs.launchpad.net/webbrowser-app/+bug/1129281

Instead, we connect to a signal from Monocle to notice these clicks,
change the document title when it happens, and detect this change from
QML and open an external browser there.
