config item for clipboard security error message

[Richard Lovejoy <xinha@…>]

You may want to specify a particular, customised error message when an exception is encountered trying to use the cut/copy/paste buttons in gecko browsers. Perhaps you'd even like a link to explain the phenomenon in detail. With this patch you have two new configuration items:

config.geckoClipboardSecurityMessage config.geckoClipboardSecurityUrl

If you don't set geckoClipboardSecurityUrl, or if you set it to null, then an alert is used to display the message. Otherwise, confirm displays the message, and selecting OK will show the URL.
