The directory layout is partially based on the C++ namespaces we're currently using. Other changes include: * devoptab: move directory into "core". * fatfs: move directory into "core". * GameCardTab: move portions of logic from PopulateList() into their own methods. * GameCardTab: use a macro to generate the properties table. * GameCardTab: use a macro to add ListItem elements. * GameCardTab: update AddApplicationMetadataItems() method to also display the number of DLCs available in the inserted gamecard for each application whenever possible. * Makefile: remove all extra entries from the INCLUDES variable. * nxdt_includes: move HOS version structs into their own header file. * tasks: move code for each individual task into its own file(s). * title: update titleGetGameCardApplicationMetadataEntries() to also count the number of DLCs available in the inserted gamecard for any given base application. * title: reorder gamecard application metadata entries by name before returning the buffer in titleGetGameCardApplicationMetadataEntries().
