Alph 1.04 - an important update

[Craig Morris]

An update to Alph 1.04 is now available on the Apple App store. This
update corrects a potentially serious problem that was introduced in
the unit conversion routines of a recent update of VMGThermo. While
this problem did not affect any of the default display properties in
Alph, it could result in incorrect values for some optional display
properties. A problem was more likely in US units, but could occur
for some properties even with SI units. Please update and check any
values from the optional display properties. Note this error was only
a problem for third party applications using VMGThermo and did not
affect VMGSim results.

Also:

Added an element array ":" to to formulas to allow an element to be
retrieved from an array. For example @feed.X : 3

Power operator had same precedence as multiply and divide. Fixed it
so it has higher precedence, but less than element operator.

Fixed problem where units would revert to SI when starting with a case
that was in US units.
