Module creation at runtime

@MaBe, indeed, after all, it is just a map or dictionary with a key and an object. I went for the string for several reasons:

1. To use the module source pattern
   
2. To be able to accept source code provided through connectivity
   
   

In conversation about Module Development I went a step further: compose a module from module components - not only to avoid possible out of memory condition, but also pull most recent and on demand what is required by the application. (A similar pattern to bootloader: application bootloader).
