Further releases will be signed and the debian watch will check
the signature. So it is necessary to add the public key.

C++ redistributable installed automatically.

Rather than forcing the user to click next, and showing them the
scary fail message if the library is already up to date, the
command line parameters make the redistributable require no
interaction.

Remove result text box
...
It was not really easy to write the name for the result
in a separate box, and it would create a lot of garbage
results, by creating a new one per every query.
Now single lines queries can contain assignments, and if not
a default relation named 'last_' is used to hold the last result.

Added function to split an assignment expression
...
In the UI, a common pattern was to check if a query was
prefixed by an assignment and in that case, assign the result
to the given name.
This function puts this in a common place, so it can be used from
all the parts where it is needed.

Changed the blur thing with a simple label

It was a bit buggy and was not blurring all the widgets, or
not reverting the blur properly. Probably best to just show a
label instead.
Still, the proper solution would probably be to do the processing
in a separate thread.

Blurs UI while processing

Before the processing of a query starts, it will blur the UI.
This gives feedback to the user that something is happening, and is
simple to implement because I am too lazy to move the processing in
a separate thread.
