[vuejs] DataTable icons should have a tooltip

[fdaugan]

In many datatables, the columns contains one to many actions and notes with their icon.

Add a simple tooltip to these icons.

Resolved by #42 (merged on 28 May). Tooltips are now wired on type, status and action icons inside DataTable cells across UserListView, CompanyListView, GroupListView, GroupMembersView and DelegateListView. Header tooltips for Admin and Write columns were already covered by commit 041d80f.
