Fixes for many issues in flowview, graphing window, and frame playback.

In FlowView:
- Drastically improved functionality of live mode. It actually works now
- Fixed several crash bugs
- Program didn't used to pick up new frames properly. This is now corrected.

In Graphing window:
- Fixed dynamic updates to work properly even under heavy bus loads

In frame playback:
- Fixed a bug where single stepping through frames didn't send them over canbus
