Field type "Table": add button to clone row

[BlackbitDevs]

The field type Table has 2 buttons to "copy" and paste but this cannot be used to copy/clone a row. You can copy the table data but in the paste dialog, the dialog window immediately closes after pasting, so you cannot duplicate a row (only if you copy table content, paste it in an external editor, duplicae the desired row and then use paste button - usability nightmare ;-) ).

This PR adds a button to clone the selected row.

Alternatively / additionally we could change current behaviour of immediately closing the paste dialog box after pasting. But still cloning a row with one button click would be a better UX.

And this PR cleans up the add / delete buttons to be in the same order for columns and rows - before it was

Add column	Delete column	Delete row	Add row

Now it is

Add column	Delete column	Add row	Delete row

I agree on the topic of the closing paste dialog, dont like it at all. Additionally we could ad some tooltips/alt texts for the icons. This should be a separate pr/issue though.
But even with those changes the clone button still makes perfectly sense to me- thanks for the contribution.
