BUG 0000 "improvements on System::getSystemConfiguration() function"

- this is a important improvement, now we can have two configurations levels
  1. Global Configuration Level (workflow/engine/config/env.ini)
  2. Workspace Configuration Level (.../shared/sites/some_workflow/env.ini)

- improvement to read env's ini files once and store on session,
- if any file has been changed (verify by checksum files) that session value is updated

(removind debug print_r)
