Exporting maps (in any format) doesn't produce a file. In Safari, nothing happens at all. In Chrome, the download has the message:

dl
Failed - Network error

Telling Chrome to resume the download changes the message to:

dl
Failed - No file

Fixed issue #31 concept map exporting not working. The new version of…
5d4cc2c 
… spring security

by default puts HTTP headers that seem to make Chrome (and probably IE too, but I
haven't tested it)--but not Fire Fox--block the download. I disabled the XSS
attack protection header. We never had this to begin with (Vaadin does not protect
against it), but maybe we should look into preserving this header while also
permitting downloads.
