BETA version no longer allows exponentiation of litsts

[Mike Elzinga]

(Still having some intermittent internet connection problems, but here are some examples.)

For Version (2021 04 28) BETA
L1:={2,-2,3,-3}
TAN(L1) gets {-2.19,2.19,-0.14,0.14}
TAN({L1}) gets {{-2.19,2.19,-0.14,0.14}}
e^L1 gets ERROR: Bad argument type
e^{L1} gets {{7.39,0.14,20.09,0.05}}
LN(L1) gets ERROR: Invalid input

For Version (2020 01 16) everything is the same except that
e^L1 gets {7.39,0.14,20.09,0.05}
which is consistent with how it works with other functions except the logarithm function.
