MDL-27001 'Show description' feature part 2 - Automatic support for modules that don't have a get_coursemodule_info function

Browse source 
If a module doesn't have module_get_coursemodule_info function, but it does have 'intro' and 'introformat' fields in its main table, then all it needs to do is return true for FEATURE_SHOW_DESCRIPTIONS and everything is handled automatically.
