Fixed bug in scan_perform.pyx

Scan_perform.pyx used not to zero out the output starting from the right point (when performing a while). This bug was detectable only in debug mode. The python version of scan was doing the right thing though, so this is just a matter of sync-ing the two versions. Note that all the changes in scan_perform.c where generated by cython, and as such they shouldn't need to be checked ( they are mostly because in the lab we have cython 0.14 instead of cython 0.13 which I used previously).
