UI Examples Update (Widget Demo v7.4.0 and MWT Examples v2.3.0)

Hello,

We recently updated two UI examples, the widget demo and the MWT examples.

This update rehauls the widget demo, adding new pages for new widgets (different types of scrolling widgets), fixing existing widgets (keyboard code and graphical touch-ups), and updating the code to use the latest UI libraries.

The MWT examples were also enriched with new examples of widgets (several types of containers, images pool, popups, and internal front panel).

Happy Coding!
The MicroEJ Team.
