Alter commit 3758306 to allow region name to be substituted within a region console prompt

This is to allow broader subsitution in the future.  Currently, the only substitions are \R (for region name) and \\ (for a single backslash)
e.g. "Region (\R) " is the current and continuing default prompt
This renames custom_prompt in [Startup] to ConsolePrompt
