Context: I have fresh installation of Fedora 25 (KDE spin). In that installation, webkitgtk3 is not installed by default. As a result of this, Central in eclipse is behaving exactly the same as in normal web browser (only some forge example is displayed (no archetypes) and when this example is clicked on, popup (this one: https://github.com/jbosstools/jbosstools-central-webpage/blob/master/src/scripts/main.js#L447) pops up instead of wizard). This leaves Central unusable.

Installing webkitgtk3 solved this issue, but it would be great if Central had some mechanism for detecting this and in case it is not able to communicate with eclipse instance it could throw recommendation for user to check if he has webkitgtk3 installed.

Maybe also document this requirement?
