[evolution] WebDAVNotes: Let the user choose which extension is used for new notes

[Milan Crha <mcrha src gnome org>]

    WebDAVNotes: Let the user choose which extension is used for new notes
    
    Rather than forcing .txt or .md extension in the code, let the user choose
    which one is preferred. Still default to the .md extension.
