Bug Report - Save files are accidentally saved while using the touchscreen

[eduardomonforte]

Describe the bug
If you make changes in a save file's Editor and touch the icon on the lower right side of the touchscreen to go to the previous screen instead of pressing the B button, your save file will be saved if you made changes to it. This happens because the button to go to the previous screen occupies the same location on the screen as the button to save your file, overlapping with it, and touching the "Press B to go to the previous screen" button will also count as touching the "Save changes to your save file". Pressing the B button to go to the previous screen will bypass this bug, as the touchscreen is not engaged with.

To Reproduce
Steps to reproduce the behavior:

1. Select a save file from the app's main menu.
2. Select the "Editor" option on your device's bottom screen.
3. Make a change to your save file, such as changing your active box.
4. Go to the previous screen by touching the "Press B to go back" button in the lower right side of the bottom screen, instead of pressing the physical B button to do so.
5. You'll notice that the changes to your save file were saved, although you didn't touch the "Save changes to your save file" button.

Expected behavior
The user should go back to the previous screen without the changes to their save file being saved. The changes to a save file should only be saved if the user touches the "Save changes to your save file" button later.
