[Feature] Add Update Now to context menu

[tomc3]

It will be great if we add Update Now to context menu. After right click on any page click update and you are done.

Updating is something to be done every few days (and it's done automatically unless you check off the setting), and has nothing to do with what appear on a web page, which is the purpose of the context menu -- this is why it is call the context menu.
