Separate the download thread from the widget logic

This is important to not duplicate code for the Qml
view. Now the DownloadFromDiveComputer widget is mostly
free from important code (that has been upgraded to the
core folder), and I can start coding the QML interface.

There are still a few functions on the desktop widget
that will die so I can call them via the QML code later.

I also touched the location of a few globals (please, let's
stop using those) - because it was declared on the
desktop code and being used in the core.
