Change tab behaviour to be consistent with other applications

[diederik]

A request to change the behaviour of tabs a little bit. This should make it more consistent with other apps like Konqueror.

• Have a close button at the end of the tab row..?
• Hitting the window close button: prompt to close all tabs, current tab only, or abort.
• Ctrl+W: close one tab.
• Esc: close one tab

If you disagree with this idea, please let me know as well.

• switching between tabs: konsole uses Shift + left/right. Firefox has Ctrl + left/right. Is there any consistency here, or can we support more options?

[diederik]

err.. correction, firefox has Ctrl+Tab, and Ctrl+Shift+Tab.

I guess supporting more ways of switching between tabs could only be a good thing.

Other than that, we could also add Firefox's alt+number way of switching; it's easy to implement too.

* another issue: mousewheel up and down are reversed compared to Konqueror.. :p

Done with r3402:

• Shift+left/right wasn't implemented (didn't work!) but ctrl+(shift+)tab was;
• Alt+number doesn't work neither;
• Added Alt+Right/Shift+Backspace and Alt+Right/Shift+Backspace to move between tabs;
• Implemented more and better warning dialogs when closing a tab and all tabs.

Oh i forgot, I've also fixed the scroll with mousewheel, now scrolling down moves right as in Konqueror.
