Resolves Issue #12630 -Added Filters to AR

- Added Territory Filter to AR report
- Added Sales partner filter
- Added Sales person filter
-Terrtory filter is needed since if you need to see AR in North Inda you get with filter not with column
-Similarly there was a need for Sales Partner and sales person filter in the AR report which is being fulfilled now.
