Label component

I have add the following modifications to the Label component

Label Component mods (file changed:Label.java)
=====================

- (added properties in the block editor) 
   - italic (Getter)
   - bold (Getter)

   - fontstyle (Getter/Setter)
     I have added this as I have always wonder why italics never worked when I set it. 
     The reason for this is italic is on available with Sans Serif.
     There are only 7 available fontstyle so that is the reason for me adding this property



Block editor block family Mods (files changed: OUTPUT_FOOTER.txt, OUTPUT_HEADER.txt)
==============================
FontStyle block family added
- This contains the 7 possibly fontstyle available.
  Used with Textbox, Button, Label components
  font styles are:
  SansSerif Normal, SansSerif Bold
  Serif Normal, Serif Bold, Serif Italic, Serif Bold Italic
  Monospace Normal

ImageAnimation added
- This is the 6 Imageanimation allowed for use with the Image.Animation block
  ScrollLeftSlow, ScrollLeft, ScrollLeftFast
  ScrollRightSlow, ScrollRight, ScrollRightFast
