clear selection cause window scroll

[yiminghe]

happen in ie6

steps: 1.place a button far below editor :

<textarea id='test'></textarea>
<div style='height:1500px;'></div>
<button>click</button>
<script>CKEDITOR.replace("test");</script>

2.insert a page-break('插入分页符') into editor

3.keep focus（cursor） in the editor and scroll to 'click button' using mouse wheel

4.click button

expected :

window does not scroll

actual :

window scrolls to editor

reason :

caused by line 184 in _source/plugins/selection/plugin.js

doc.selection.empty() causes scrolling.

we should record scrollTop and scrollLeft before empty() and restore them after empty() , i provide a patch ,hope helpful.

This issue has reproducible in IE6 and IE7 from CKEditor 3.2.1.

1. Copy attached TC to samples folder
2. Click inside editor
3. Insert page break by clicking on a toolbar button
4. Scroll down to button and click on it

Result: Browser will scroll up to cursor location.

Problem is still reproducible on latest trunk.
