v1.2.5 - Save System Overhaul

- Added more donors as usual.

- Added additional credits.

- The save system has been overhauled. Though this doesn't apparently affect anything, internally the way that objects are assigned has been changed so that future updates will not break previous saves. This means that going forwards, you can use saves between versions.

- Reflecting this, the "version" parameter on save files is now defunct and no longer used. DO NOTE THAT THIS MEANS THAT SAVES 1.2.4 AND BEFORE WILL STILL BE ABLE TO BE LOADED, BUT WILL NOT WORK.

- To compensate for this, you can download a save for the second part of the first episode, if you would like. This bonus download will be available until version 2.0.0 is released, whenever that is.

- The music player has been tweaked so that alternate titles for certain tracks are displayed.

- I've noticed that people have been confusing the checkpoint prompt for an autosave or a place someone can return to if losing the case, which it isn't. I was afraid this would happen, and in hindsight I probably shouldn't have called these things "checkpoints". As a result, the word "checkpoint" has been removed from the prompt; now they simply say "Next save will resume from this point".

- Apparently cross-examination 3 of part 1 is still a bit difficult so it's been tweaked to be a little easier again.
