Free42

Fixed a crash while handling nested lists.

Implemented RE, IM, and CONJ.

0=? and 0≠? now accept complex numbers, real and complex matrices, and lists.

X=? and X≠? now consider a and a+0i to be equal.

Note that these changes do not apply to X=0?, X≠0?, X=Y?, and X≠Y?, for the sake of HP-42S compatibility.

Be sure to check the Free42 web site for the 3.5 release notes as well.
