Cleanup: Remove global QFuture from exportFuncs

Browse source 
When exporting dives we show a message. The message is closed when
the export is finished. This is coordinated by a QFuture. Instead
of keeping a global QFuture in the export-code, pass it around
as a local variable.

This is supported according to Qt's documentation:
"QFuture is a lightweight reference counted class that can be
passed by value." and the source code indicates the same.

Not only does this remove a global, it also makes the code
more flexible: Now we could show one notification per export,
for example.
