Wrong result on complex power.

[GoogleCodeExporter]

What steps will reproduce the problem?
Evaluating something like (-0.27 + 0.66*i)^2 gives wrong output.


What version of the product are you using? On what operating system?
muParserX 2.1.6

Please provide any additional information below.
The problem lies on OprtPowCmplx::Eval which tries to remove the bogus results 
comparing the imaginary and real parts with the smallest numeric limits. If 
some part of the number is negative it'll consider it a bogus result and 
eliminates it. The solution is to take the absolute value.

Thank you for reporting this. I will fix it soon. The bug has exposed a minor 
flaw in the unit test which i need to address first in order to eliminate it 
once and for all.
