A function added by the New Vegas Script Extender.
Replaces occurrences of an old string with a new string within a string variable. Both the old and new text is passed in a single format string argument, separated by a pipe character as in "Old|New" (when calling from the console, use '@' in place of the pipe character).
By default this function replaces all occurrence in the entire string and is case insensitive. Optionally, a range may be specified by start character and length thereafter, a case sensitive flag and a maximum occurences to replace may be provided.
Note that this function modifies a string_var in place, and returns the count of number of replacements as an int, not a new string. Added by NVSE 4.1.
