Detailed Description

To implement a new loader, inherit from the Loader class and and reimplement canLoad() and load().

For registration, put into the static initLoaders() function of this base class a _loaderList.append(new MyLoader()).

matchingLoader() returns the first loader able to load a file.

To show progress and warnings while loading, loadStatus(), loadError() and loadWarning() should be called. These are just shown as status, warnings or errors to the user, but do not show real failure, as even errors can be recoverable. For unablility to load a file, return 0 in load().
