Continuously backup changes and load them when GRIP is launched

The only problem I forsee is if the backup file turns out to be corrupted or mal-formed then it makes it impossible to load GRIP without deleting this file.

@JLLeitschuh Well this is a pain... different save files of the same project aren't guaranteed to be textually identical, even if they're functionally identical. I want to be able to compare a previous save file to the backup to determine which one to load (backup if it's different from the previous save, otherwise the previous save).

Can you use time modified?

Never mind, all changes are automatically saved to the backup files anyway
