Modified "Display Filename And Layer On LCD"

This is a modified Display Filename And Layer On LCD script to offer a wider range of optional information.
Tried and tested on a Tevo Tornado (Running Marlin 2.x.x)
2 new options
- Scroll (If scrolling LCD is enabled)
- Max Layer (To display "Printing [name] - Layer # of ###")

-# Description:  This plugin inserts a line at the start of each layer,
+# Description:  This plugin shows custom messages about your print on the Status bar...
-#               M117 - displays the filename and layer height to the LCD
+#               Please look at the 3 options
-#               Alternatively, user can override the filename to display alt text + layer height
+#               - Scolling (SCROLL_LONG_FILENAMES) if enabled in Marlin and you arent printing a small item select this option.
+#               - Name: By default it will use the name generated by Cura (EG: TT_Test_Cube) - Type a custom name in here
+#               - Max Layer: Enabling this will show how many layers are in the entire print (EG: Layer 1 of 265!)
