[Merge] lp:~osomon/webbrowser-app/uriboni-tab-context-menu into lp:webbrowser-app

[Riccardo Padovani]

Review: Approve

lgtm now, thanks!

just a very little thing (tbh, I don't think it's fixable): you disabled the x dragging while right clicking (and that's perfect) but if I press right click and before releasing it I middle click the tab is closed (I expect it is ignored)
