the mouse over the text/box.
- the text will now zoom and scale correctly, same goes for the icon and
the compartment for the title and stereotype

- useless keywords
- code clean//overrides
- need fix bug : strange zoom please refer to TMLComponentDiag to change
code

Cleaning code and adding/fixing documentation:
- more precision
- unnecessary element removed for more readability
- as for issue 31, fixed the logo resizing for avatarPDBlock
