cf2115b383 Do not crash if the returned remote version is None 
That happens in case of errors.

Now it correctly shows an error.

ba8453c923 Print optimization steps 
Prints the various steps on stdout, quite nice to
be able to understand what is happening internally.

5563e1cafd Do not add query to history if it was the last

This is the behaviour of bash.

474bea6ff5 Re-unite query execution functions 
For multi-line and single-line. After the change with the assignment
they are basically the same and there was no longer need
to have them separate in two functions.

67db598b02 Shortcut to show relation 
Pressing space on a selected relation shows it.

I wanted to use 'Enter' but it doesn't work.

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.

e017949f7d Navigate history with arrows 
In single line query mode, the history can be navigated
in a way that is somewhat similar to the shell.

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.

be8230d54a Align query editing box with relation viewer 
Not sure of what the problem was, probably some layout or frame that
had spacing.

Replaced the whole mess with a stacked widget instead.

f5ef1027d0 Refactored main window creation

multiple steps to be taken from the main module.

be7e6fe12d Classes have now names that begin with uppercase 
This is more Pythonic and makes the code more readable.

Backwards compatibility is provided by giving an alias with the
previous name of the class.

It will not be broken until the next major release.

3060a8562f Ask for relation name if filename is not valid 
By default when loading a file, a relation with the same name is
created.
Now, if the filename is not a valid relation name, the user will be
prompted to manually insert a relation name.

De-duplicated code for doing this when a new relation is created.

8102dbe959 Fixed and changed semantic of open relation 
Now relations are always named with the default name.

Multiple relations can be opened at once from the GUI.

Removed redundant code to select the default name for a relation.

Using system dependant splitter to determine the default name for a relation.

The GUI is still somewhat buggy, and it can't open files yet,
