Wcalc

Many small bugfixes, improved C-like bitwise operations, and stability fixes. The input internationalization is now allowed to be different from the output internationalization.

Several display glitches with auto-resizing for
large numbers have been fixed, as has the
simple-calc mode. Engineering notation and
non-number input (such as @NaN@ and @Inf@) have
been made more reliable, as have some multi-step
operations. The licensing has also been updated to
be GPLv2+ compatible.

This has plenty of bugfixes and a couple nifty new
features. In the GUI realm, Wcalc now also serves
as a System Service, and so adds a "Wcalc Compute"
entry to the Services menu of other applications.
In the CLI realm, Wcalc's error reporting is now
more friendly, and will tell you exactly where in
the line the error occurred. Also, Wcalc now uses
tab-completion in the CLI, and can tab-complete
just about anything (variables, conversion units,
commands, functions, etc.).

The mod operator (%) is both efficient and C99-compliant now, and can be configured to treat negative numbers two different ways. Inspector is now a panel, which can be copied from. The negative exponent bug is fixed, and hexadecimal exponents can now be expressed easily (with the @ character). Several small bugs are also fixed.

The crashing bug in the persistent variables
window was fixed.
