Allow disabling notification grouping.

[ZenerDeveloper]

I love using this app and the concept of putting reminders into the notification panel, which is frequently checked, is great. However, after adding more than 3 notifications, they automatically group into a single one. This makes it more difficult to see how much you need to get done as it only shows 2 reminders without expanding, or none if set to minimized (how I like it set). Attached is a screenshot showing the difference between 3 and 4 pinned reminders with notifications set to minimized. You can see it shows the titles until they get grouped when it only shows the app name. Changing this is as simple as using .setGroup() with a unique string on each notification (such as the title, description, or both) to keep them all separate. It's a simple feature to add and, if there is a reason to group notifications, you could easily add a preference value and a check to the notification builder to allow the user to enable / disable it. Attached is a screenshot of my one-line modification adding .setGroup(notification.title + content) to the builder
