    Add some minor optimizations.

commit cc308418b3e239e05a7f1f0f6cfc5919672fccfd
Author: Richard Kreckel <kreckel at ginac.de>
Date:   Thu Nov 5 13:30:48 2015 +0100

    Speed up power::real_part() and power::imag_part().
    
    Add special case for real base and exponent (not just integer exponent).
    Improve special case for integer exponent by explicitly constructing
    the result using the Binomial expansion.
    Add a test case for real/imaginary part expansion.
