Feature Request: Sorting of contacts in web view + general feedback

[PartisanEntity]

In the web view, when viewing "All contacts" it would be nice to be able to sort by date created, first name, last name, group, etc..

Also as general feedback, it would be nice to have some consistency. For those of us who have been using Owncloud for many years now the contacts are rather confused. Newly added contacts have different fields than older ones.

I have also started seeing new groups appear with just an alphabet such "D", "S". If this is an owncloud feature then there should be a service that goes through all contacts and sorts them and cleans them up. If however it is a misconfiguration on my end I would be happy for any pointers.
