1c9c9a7195 Remove osx mention from README 
No apple user is ever going to make a contribution and tell me how to run
this thing on osx. Let's forget about it.

can fail.

This shows an appropriate message.

6b4cfaa01d Added my public key in the debian/ directory 
Further releases will be signed and the debian watch will check
the signature. So it is necessary to add the public key.

af7901423c 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.

1dd1298ee0 New optimization: useless projection 
If a projection is done on every attribute it is useless and

3b3888e9be New optimization 
Turns
        π a,b,c(A) ∪ π a,b,c(B)

    into
        π a,b,c(A ∪ B)

    if A and B are union compatible

Works with union, intersection and difference.

a30aac5f5b 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.

e3877a4682 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.

7acc0d19d0 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.

239e0e58dd 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.
