HIG: tabwidgets

[Maks Orlovich]

> Action		Shortcut		Required
> -------		---------------	-----------
> New Tab		Ctrl+Shift+N	Yes
> Detach Tab	Ctrl+Shift+D	No
> Duplicate Tab			No
> Reload Tab	F5		No
> Next Tab		Ctrl+Left_Arrow	Yes
> Previous Tab	Ctrl+Right_Arrow	Yes

konq currently uses Ctrl+Shift+D for duplicate tab, because Ctrl+D is 
duplicate window, with Ctrl+Shift+B being detach. Any reason not to keep 
that? (I don't think other apps have those shortcuts).
