Produce cleaner code in Editor

The WYSIWYG-Editor is massively producing statements like '(% style="font-size: 11px; font-style: normal; text-align: start;" %)'. Even when just working with the standard toolset from the toolbar. Inspecting the code in the source view becomes annoying, as well as changes in the WYSIWYG-Editor often not leading to expected results.

This behavior is also noticed when copying simple formatted text from the WYSIWYG-Editor as source to the WYSIWYG-Editor as destination.

Try to keep the syntax as easy as it could be and avoid special statements. Also there is no option for pasting text as plain text.
