Title: Qlist fixes

@lilvinz and I spent some time with Valgrind, and discovered that Qt's QList container isn't very efficient for iterations. This document gives good background on what's going on: http://marcmutz.wordpress.com/effective-qt/containers/

We changed the QVector to QList, changed the loops from incrementing indices to incrementing interators, and factored out some calls that were being done on a per-loop basis, even though they only needed to be called once. Note: these last are probably optimized by the compiler when compiling release versions.

Tests were done using HiTL.
