Option to choose the web browser for links

[diederik]

By request, it should be possible to choose a browser where links are opened in (e.g. because Hotmail works better in some browsers).

Amarok has a nice example how this can be implemented as dropdown box:

• use KDE default
• use Konqueror
• use Firefox
• use Opera
• other..

it only displays the browsers which are detected at the system.
