Title: Fixed an issue when integrating Abs(x) - Google Code-In

Integral(Abs(x), (x,-1,1)).doit().n() would not return the integral of the absolute value of x from -1 to 1 correctly.
-->Any integral of Abs(x) from a negative to positive bound with same absolute value would not be returned correctly

Here is my fix for the Google Code-in
