[Feature request] Option for Ctrl+T, use context from active tab

[Zamralik]

Could you add an option that change how Ctrl+T works ? When the option is ticked, whenever you use the shortcut to open a new tab, it'll open it in the same context than the active tab.

I'll have to look into this one. It seems like it should be possible, unless FF doesn't like you overriding default keybindings.
