Scheduler system improvements & bug fix
1. Fix: Cancel Job requests (issued from System->Scheduler->Active Jobs menu) were not working on all app servers. Implemented a table to allow kill job requests to stop the job regardless of which server in the pool is running it.
2. Added a column to the Active Jobs and also Process History screens to show which server a job ran on.
3. Misc sizing/alignment GUI fixes on the Active Jobs and Process History screen.
4. Moved ""Process History"" top menu item directly under the Processing main menu for easier navigation.
5. Removed the process alerts tab from the Process menu, the recommended way to manage process alerts is on the main processing screen (for example Exports, Imports, etc).. using the envelope icon on a selected schedule.
