4876	Better support for pasting text with tabs	Wiktor Walc		"Problem: when pasting text with a tab, tab is changed into one space in IE (or space surrounded by `<span>` in Safari).

Sometimes users are using tabs to indent text. After creating text in notepad (for example), they copy that text into the editor... and notice the problem that text is not anymore indented as they expected it to be (tab is not shown as 4 spaces or something like that).

Instead of changing tabs automatically into one space, we could change them into configurable number of spaces (in a similar way like it is possible to set editor.config.tabSpaces).

=== Steps to reproduce ===

 * create the following text in notepad:
{{{
Test<tab>Test
Test<space><space><space><space>Test
}}}
 (where `<tab>` is simply a tab)
 * copy and paste it in the editor
 * result in IE8:
{{{
<p>
	Test&nbsp;Test<br />
	Test&nbsp;&nbsp;&nbsp; Test</p>
}}}
 result in Safari 4.0.4:
{{{
<p>
	Test<span class=""Apple-tab-span"" style=""white-space:pre""> </span>Test</p>
<p>
	Test &nbsp; &nbsp;Test</p>
}}}
