de405480b5 Moved casting function in rstring 
rstring now has an autocast() function that returns the automatic casting
for that value.
The casting is cached so is really performed only once, at most, during
the lifetime of the object.

be6400c270 Mark both relations as read-only after a rename 
Only one relation was marked as read-only after a rename, which means
that changes to the original relation would affect the other one
as well.

4af2230ced Use rstrings anywhere 
Since rstrings are faster and provide some caching features,
keep the same rstring objects from the beginning rather than
continuously casting strings.

19cff69718 Cache type information on strings 
During a selection operation, each value is matched against a regular
expression and then casting might be performed, depending on the results.

This commit caches the result of the match so that a value is not matched
multiple times in its lifetime.

bf13fe0c4a Remove manual font setting 
It is a workaround that should not be necessary.

However, maybe it still is, on windows.

f3af25f132 Support multi-line editing mode 
This mode supports the insertion of multiple queries in one shot,
assign them to variables and reuse them.

Basically a program. Less interactive mode but better for more
complicated queries.

8cb08ad030 Change relational language to use math symbols 
The symbols previously used were a Canadian script, and were looking
good enough, but they might not be installed in every machine.

Besides, all this is to workaround a Qt5 bug that prevents from
rendering those symbols at times.

cf377eca46 Initial Qt5/Python3 switch 
This converts the GUI code to use Qt5 and Python3

The GUI is still somewhat buggy, and it can't open files yet,
but seems to be mostly working, extensive testing will
be needed before this can be released.
