Fixed properties stepping and autogenerated properties skipping

* Do you think "frame.StackFrame.ILOffset == 0" is robust enough? Can ILOffset when we just step into property not be 0?
* Do we want to skip auto-properties when StepOverProperties is disabled? I asked VS team what they think :D https://twitter.com/davidkarlas/status/546540766164971520 Imo it's regression
If both answers are Yes... It's OK to merge imo...
