[Webkit] Cut&pasting text adds inline wrappers

[Matthew Leffler]

This is basically the same as #9754 except that it requires config.contentsCss.

Steps:

1. Add problem.css to the samples folder
2. In the replacebycode.html sample change the JS to CKEDITOR.replace( 'editor1', { contentsCss: 'problem.css' } );
3. Viewing the sample page, cut a word from the now red colored text and paste it back into the text.

Expected result: The source should be unchanged.

Actual result: The pasted text is now wrapped by <span style="color: rgb(255, 0, 0);">...</span>.

Notes:

• Pasting using the Paste from Word command has the desired effect. (Removes styles but doesn't remove a link for example.)
• Is it possible to make Cmd+V, Ctrl+V paste as if Paste from Word? I know of config.forcePasteAsPlainText but that would remove links, as well as styles.

Unlike #9754 I was able to reproduce this problem from CKEditor 4.0 beta in Chrome and Safari 6 Mac (Safari 5 Win seems to work fine).

Unlike #9754 I was able to reproduce this problem from CKEditor 4.0 beta in Chrome only.

@j.swiderski I'm able to repro this on Safari 6.0.2 on Mac OS X ML.

@mattleff thanks for the hint. I will recheck this on Mac and update comment if necessary.
