Ability to manually enter line spacing or line per inch for a Map Field

In this enhancement, line spacing can be manually changed the following way:

Check the “Automatically calculate Line Spacing with selected font” check box. With this option, the line spacing is calculated by means of the current font size and font height. (This is the process that is currently used when a font size or font name is changed).
Enter line spacing.
Select Line per inch using one of the options in the pull down menu.
