Bug Fix: If DB connection fails at startup the Application Web server consumed 100% CPU

Added case in FRCts20_Backend_Error_Handler.vi to handle error
-2147467259 for an incorrect password, etc. in INI file.

Edited FRCts20_Backend_Failsafe_Handler.vi to open/create file. Changed
target location for error file and write all errors to “errors.txt”.
