v1.3 approved

[Calc Zero]

Apple has approved the update in record time--only 1.5 weeks.

Lots of good stuff in 1.3:
New Memory functions (touch and hold to access additional
functionality);
New preferences: text display color; key shake on/off; adjustable
threshold for display of scientific notation;
New H.MMSS and M.SS keys for easier entry of Hours:Mins:Secs and
Mins:Secs;
New pop-up submenu for x squared/square root key (touch and hold to
access additional functionality);
revised Scientific mode keys;
New RLC mode (with common EE units and series/parallel operator keys);
Improvements to upside-down spelling mode;
Misc. Bug fixes and UI improvements.

Now I need to get to polishing v1.4 for release. Highlights in 1.4
will include the ability to customize many of the unit buttons, many
more currency units, and a programmers mode (with bitwise operators
and hex/bin/oct conversions).
