LED component

[nmarquesin]

When we created our hello world tutorial for embedded systems, where a button switches an LED on and off, we needed to use an image to represent the physical device.

To create simple tutorials like that for embedded devices with TotalCross, it would be nice to have an LED component that is easy to call and use on these starter GUIs, for people to experiment.

@victoriaingrid-del was kind to think for us how this component could look like, and here is what she did:

I really like the colours she picked, inspired by the Bootstrap colour design.

This would be a fun feature to introduce in TotalCross V7, as it provide a cool component to be used in getting started tutorials 😃
