[FR] Add multiple app support for sentinel monitor and drag/drop

[bio1020]

Describe the bug:

The Trash Sentinel function does not recognize deletion of multiple APPs at one time.

Steps to reproduce:

1. Go to '/Applications'
2. Choose two applications
3. Move them to Trash
4. Pearcleaner will automatically open, prompting you to delete one of the applications. After clicking the uninstall button, you will no longer be prompted to clean the second application.

Info:

• OS: 15.1
• Pearcleaner Version: 3.9.3

So this isn't necessarily a bug, it's how the app logic is currently designed. It can only ingest one path at a time.
If I remember right, I think dropping multiple apps on the Pearcleaner window has the same behavior where only one of the apps will be recognized.
I will look into adding support for multiple paths in the future for drag/drop and the trash monitor.

I added some logic where if you Trash or drag/drop multiple apps, it will queue them up in a list at the bottom.
When you delete the first one in the list, it will then load the next one. I also added the ability to remove them from the list using the minus buttons.

I'll have this out in the next release.
