String_Truncate takes three parameters: an input string, a -Length integer, and an optional -Ellipsis string. It returns a string no longer than the specified -Length, appending the optional ellipsis if the string is actually truncated. If the input string is shorter than the specified length, the full input string is returned and no ellipsis is appended. Note: The length of the ellipsis is not counted when truncating the input string. The string is truncated to the specified length before the ellipsis is added.

Note, this is a port of John Burwell's tag for 8.x
