Ability for promoters to log in and get sales reports on their shows

We now have functionality in place to allow promoters to log in to the admin section of the site and see Report Shortcuts that have been specifically set up for them, even if they have no other admin rights and no access to any other parts of the site.

Reports can take into account which user is looking at them and return data based on the current user. This means if we set up a show as having a promoter on the system we can enable them to see their shows, or, if we prefer, schedule reports on their shows’ sales returns to be emailed to them at regular intervals.
