User View and Functionality Needs Updating to Match v5

The current v6 User View UI design and functionality complicates and restricts everyday operations. v6 Needs to be updated to better match features avaialble in v5.

Essential changes are:

  1. update view to include column for Name.
  2. update view to allow sorting on column headers as per v5
  3. change user item  'save' functionality so view returns to previous state prior to record being opened. (e.g. if a search has been done to user name 'Alice' then when the 'Alice' user record has been edited and closed system should be display view with 'Alice' showing in same state as before user record opened rather than returning to default user view layout)
  4. 'mass actions' functionality in v5 user view needs to be added to v6
