Applying updates for Libero SoC support (#1855)
* Updated the new_project tcl function and removed set_device function. * fixing tcl command set_root and adding in build_hierarchy command. * Adding tcl command to export_prog_job file for FPExpress, saves in Libero SoC default location. * Attempting error checking on Libero SoC installation, and typo clean up. * Fixing -adv_options in new_project tcl command. * Moving script_ext back to its original location. * Commented out Libero environment variable. * Removed Libero environment variable.
