confirm: Generate confirm dialog

Generates on MSIE>3 a vbscript confirm dialog before the user may execute a critical link or form. Non IE clients will produce a standard confirm() dialog.
When the normal javascript confirm() dialog is used there is one danger: the default button is "YES" and thumbfingered users may confirm unwanted. A better approach is to generate a vbscript (for them IE users) dialog and call this dialog using javascript. So the programmer can change anything in the appearance of the dialog, even the title and better: the default button may be "No". This class tries to see what browser is given.

Confirm will generate the standard javascript confirm() dialog on non-vbscript-browsers. At the moment only MSIE > 3 is allowed to generate the vbscript dialog in this class, maybe some research reveils other browsers which also support vbscript.
