IE: Right click on selected content not removes the selection.

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.

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 fixed this action is now permitted.
