Ability to backup, restore, and uninstall a single app

[joe4dev]

Currently, backup, restore, and uninstall can only be performed for all apps together.
It would be extremely helpful to perform these operations selectively per app:

• mackup backup => mackup backup git Backup a specific application #611
• mackup restore => mackup restore gitBackup a specific application #611
• mackup uninstall => mackup uninstall git Can't remove sync settings from mackup #692 , [ QUESTION ] - Remove a config file from Mackup? #1069

This is kinda the bottom-up approach to #608 (enable/disable) and would facilitate development (e.g., smoke testing) of single configurations remarkably. Especially when modifying/overwriting configurations, we need a tool to mackup uninstall git and mackup backup git again.

This was addressed in PR #968 but never completed. I think this can be implemented without introducing any backward incompatibilities in a first step (before migrating to a status-based #603 enable/disable #608 approach as proposed in #614).

I agree with another comment that this is one of the biggest missing features.

So uh, how far are we with this?

I could be wrong as I haven't actually used this software yet, but it would by my understanding based on reading the documentation that you could simply create a mackup config file (if you don't have one already) and add the single app under applications to sync. I believe then running backup, restore, or uninstall would only apply to that application. If you already have a config file with a list of applications to sync just comment out all of the applications aside from the target application before you use the commands...then uncomment them when you're done.
