Copying text from MS Word always creates a new text element, even when the cursor is inside an existing text element

Migrated from: https://bugs.launchpad.net/inkscape/+bug/491716

Steps to reproduce:

• open Inkscape
• create a text object and type something
• open MS Word, type something and copy to clipboard
• place the cursor somewhere in the text field in Inkscape
• paste

What happened?

A new text object is created.

What should have happened?

The text is inserted at the position of the cursor.

My best guess: the EMF import is invoked on paste, creating a new text object.

Suggestions:

• When the text tool is active, query the clipboard for a text representation. Else, use the EMF import
• When the text tool is active, check the EMF import: If it contains only one text object, in that case, paste in the text box. Else, paste the EMF import

#1587 is the opposite: a new text element should be created when pasting text from a non-EMF-providing application.
