Update #45(a)

Whats done:
Added Benchmark in admin, started implementation of Supervisor page,
updated open-benchmarking views.

Requirements:
1. When creating a new record for a year that does not exist then NULL
BM values are initiated. But not initiated all the time when a facility
creates a new record as long as the BM_year already exists.

2. Active/Inactive facility option: this will help in analysis of
different hospital levels as well.
