Adding Character Spacing

Adding Character Spacing

***********************************************************
Description:
Adding the CHARACTER_SPACING for text-editor, text-field and text-label.
CHARACTER_SPACING determines the spaces between characters.
A positive value will make the characters far apart (expanded) and a negative value will bring them closer (condensed).
The sample code below can be used to test the CHARACTER_SPACING.
