- Various cleanups/refactorings to Loader, ELF, and NCCH modules. - Added AppLoader interface to ELF and NCCH. - Updated Qt/GLFW frontends to check AppLoader ResultStatus. NCCH: Removed extra qualification typos. Loader: Removed unnecessary #include's. NCCH: Improved readability of memcmp statements. NCCH: Added missing space. Elf: Removed unnecessary usage of unique_ptr. Loader: Removed unnecessary usage of unique_ptr.
