Bulk-delete contacts

[didyouexpectthat]

Is your feature request related to a problem? Please describe.
I imported my contacts from Google, but I had businesses in the vcard. I notice that Monica is not really into businesses, just people. I was looking for an option to bulk-delete the business contacts but I have to delete one contact at a time. I have about 37 businesses saved so it's a lot of clicks just to delete these 37.

Describe the solution you'd like
On /people, allow me to multi-select contacts, then show me what I can do with the selected contacts:

• Add contact to a tag
• Remove contact from a tag
• Delete contact

Describe alternatives you've considered (optional)
I can't think of an easier way to manage many multiple contacts.
Otherwise, support Business interactions.

Additional context
See photoshop magic at its best.
Maybe a select all in this filter option, too...
