Optimizations Part 2 - On the hunt for the mid-workout time slippage bug. — Boot Camp Fitness Steam update #324453

* Sprites and graphics added into texture groups to cut down on texture swaps. * A few cases of unneeded double coding corrected. * Changed delta time code to be hard-coded into the blue bar object instead of through a script. * Referenced global variables in the blue bar object with local variables. * Referenced global variables in award check code with local variables. * Transition scripts scrapped and hard-coded into each exercise object. * + various other small optimizations. This wave of optimizations was focused on creating texture groups which will help with the performance of loading sprites a little bit, cutting down on script calls and referencing global variables with local variables to hopefully increase performance slightly. Still trying to beat the time slippage bug mid workout that some players are experiencing. It has not been happening to me when testing but it did happe...
