When running loadBackup, instead of always stashing, add configurable setting to abort if there are changes #13
Description
When running loadBackup, currently it always starts off with stashing. We would like to add a configurable setting, to detect if there are any uncommitted changes in your current git repository. If there are, abort the loadBackup. And by creating the setting, the user gets to choose if they always want to stash, or they want the loadBackup to fail in case they accidentally called it.
