Commit 6 - More tweaks to attraction behaviors.  Made DetalTf not show until after freeze happens.  Added repeller's to beaker 2 and 3 edges to push particles toward middle when freezing, also increased center strengths for beakers 2 and 3 every frame after the freeze process starts - this is to address the intermittent hanging of some particles when they should be moving to the middle.  Changed Periodic Table button to Assistance button and added the image for that button.  Updated the help button info.
