Port to WebKit2Gtk

[Jiří Janoušek]

Porting to WebKit2Gtk would solve issues with incompatible GTK+ 2 based Flash plugin (#904505, #1058586, #1173963).

Porting notes:

* Stable WebKit2Gtk API is not available in Debian 7 and Ubuntu 12.04-13.10. Since Nuvola Player should run there, it will be necessary to maintain both WebKitGtk and WebKit2Gtk ports.

* API for creation of a bridge between Nuvola and JavaScriptCore was introduced in WebKitGtk 2.2:

* WebFrame is gone, WebExtension & WebPage have been introduced. https://lists.webkit.org/pipermail/webkit-gtk/2013-February/001365.html

* WebKit2Gtk hasn't support Windows yet.

* WebExtension example: https://git.gnome.org/browse/epiphany/tree/embed/web-extension

Since development of Nuvola Player has been discontinued [1], I'm closing the bug tracker. It will be reopened when a new maintainer is found. I'm sorry I wasn't able to address this issue.

Although I know progress for this is already underway, have you considered using Chromium Embedded Framework?
https://code.google.com/p/chromiumembedded/

I realize that this requires a VAPI to be created for the C API, but given the C++ and Java interfaces, this should be about two to three days of work at most. Integration would be the longest task.

I just thought I would offer this as an alternative if WebKit2Gtk ends up being a pain to use.

Another benefit would be the ability to use Pepper Flash from Chrome. Pepper Flash also works with Chromium/Chromium Embedded Framework, so you would have a reliable, updated, installation of Flash Player on every distro after a download and a quick license agreement.

I've considered CEF, but it is not available in Debian/Ubuntu repositories.

Issue is fixed in Nuvola Player 3 Beta. http://tiliado.github.io/nuvolaplayer/documentation/3.0.html
