Retest webkit suitability

Description
Webkit support for GTK+ has been bumped to WebKit 2.4 with a new package. This is available in the latest Buildroot (2016.02). We're at 2015.02. So a bump in Buildroot may provide a webkit enabled surf package, meaning we could replace the C interfaces for appmgr and videofe with web-enabled interface, making icon handling easier and providing a more developer-friendly API for extending these.
We need to investigate if bumping Buildroot to 2016.02 and re-adding the surf package (custom package) will now work. Previously this didn't work. But the reasons I suspected for it not working appear to be fixed if you look at the list of changes associated with webkit in Buildroot.

I didn't find much value in using webkit, mostly because of the overhead it brings (lots of build dependencies, etc.). So after testing I checked the changes into a new branch in the pibox repo: "mjhammel/br-2016-05". The build works on hardware, if I remember correctly. It just didn't have any added value with respect to webkit.
I can revisit this later when I migrate to a newer release of buildroot (like, say, the 2017.02 release).
There are now other options besides webkit. One is V8 + electron. This is a self contained nodejs package with GTK rendering engine. It's available for ARM. The downside is the size of the applications. A hello-world was 170MB.
There are also other rendering engines like Gecko, Blink and NetSurf, however it's not clear how to use these to build an app.
I still think using browsing technology just complicates a purpose built device. Using C/GTK/Cairo is simple enough and far more lightweight. Other than the omxplayer package, the largest opkg I have is piclock (which has themes) that clocks in at just under 2MB.

PiBox will never use web technologies as they are too heavy weight. So there is no need to retest webkit.
Closing issue.
