Switch to PSR-4 autoloading from classmap

The Symptom

After activating the plugin and reloading the page, I receive the following message:

Fatal error:  Uncaught Error: Class 'OSDXP_Dashboard\OsdxpModuleUpdateChecker' not found in includes/utils.php:31

Possible Cause

The class files are not being loaded. The includes folder is listed as a PSR-4 root, but none of the classes in this project follow PSR-4.

Suggested Solution

• Switch to PSR-4. It is a much better and more widely used convention. Any convention, including PSR-4, would allow easier loading of classes without the need to generate autoload maps.
• Another option is to add includes as a classmap root instead of PSR-4. This will generate a map of all classes contained in all files in that folder, recursively, to their filename. It would require re-generation every time a new class is added, or a class file path is changed.

Remarks

This problem does not seem to manifest when installing the plugin from dist manually, or from source via cloning. It manifests when this package is a dependency of another package. While this is issue is indeed an issue in its own right, it currently manifests due to #16.

hotfixed in 1.0.1, keeping this open since we need to switch to psr-4 rather than classmap

Oh, that would be wonderful! Let me know if there's something I can do to help in general.
