Filters for the overview/tags for medication

[Futsch1]

Is your feature request related to a problem? Please describe.
When managing medication for more than one person, it is hard to keep an overview of the upcoming and taken medicine.

Describe the solution you'd like
Medications could get a setting that add something like a tag to them that could in turn be used for filtering on the overview page. This would be more generic than adding a user mechanism to the app and might also serve for further use cases keeping track of a big set of medication.

As a further feature, it should be possible to activate/deactivate all reminders for all visible medicines. This way, medicines for certain conditions can be tagged and then activated or deactivated when the condition appears or disappears.
