Add a checkbox to allow Import to replace all existing sites

[pmierau]

At home I use a desktop computer for development, but when traveling I use a laptop. As my site list changes, I want to export from Filezilla on my desktop and then import on my laptop, replacing all of the existing sites. However, import ends up duplicating any sites that already exist on the laptop so I have to laboriously delete every site manually in the Site Manager before importing.

My request is to add a checkbox in the Import dialog that indicates that all of the existing sites are to be replaced by the sites in Filezilla.xml.
