Reorder functions and some variables
For a fresh start it seemed a good idea to cleanup the order of functions and some variables so that those with the same functionality are somewhat grouped. Some of the functions have now a header and a foooter to make it easier to spot and use then. Also for added future functions the hope is that they will be put where they better fit
