Bugfix RT53267

Right clicking on selected content should not remove the selection in IE

The problem was that ‘beforepaste‘ event was thrown when right clicking. The ‘beforepaste‘ event was
used to copy/paste content for IE. With this fix the ‘beforepaste‘ event is not necessary any more, the
whole copy/paste process is done in the ‘paste‘ event. This solution is only for IE8 and below. For
other IE versions (9 and above) the event ‘beforepaste‘ is still needed.

Bugfix RT57958

align-plugin: Alignment inside table cells is now permitted.

Setting alignment inside a table cell was not permitted unless the cell content was wrapped inside a
block element. With this fix this action is now permitted.
