Scripting; added new WordWrapText function

A new WordWrapText function has been added to Text Utilities.

This splits the text value into multiple lines breaking at whole words (if possible) no longer than the maximum line length specified.

NOTE: Compare to the existing WrapText function which does not break at whole words.

Example code:

NewValue = finBL.Runtime.TextUtilities.WordWrapText(Value, 50)
