(1) Fixed multiple free variable problems (os, re, shutil, string, time, cdsname, run_sql, acc_authorize_action, functionStop, functionError, Get_Field, forge_email, send_email). (2) Fixed Mail_Submitter.py newrnin reading, featuring read() instead of fp.read(). (3) Left Request_Print problem as is, for this function is defined in the WebSubmit engine core (see FIXME). (4) Removed explicit execfile() statements from the functions. (5) To fix the free variable problems to the full satisfaction, the global variable usage should be fully removed.
