do feature detection of paste event support before simulating a paste event

[hallvord@…]

I think this code might end up confusing you when Opera one day supports 'paste' events:

​http://dev.ckeditor.com/browser/CKEditor/trunk/_source/plugins/clipboard/plugin.js#L141

I suggest adding some additional feature detection - perhaps

if ( CKEDITOR.env.opera && ! ('ClipboardEvent' in window) )

or something like that.. There is no rush, paste event is high priority but probably won't happen for Opera 12 unfortunately.

Leaving this as a bug as in future when Opera introduces this event this issue might become a bug.
