Other changes include: * Codebase: move JSON parsing logic from config.c/h to nxdt_json.c/h. * Codebase: replace all calls to localtime() with localtime_r() to guarantee thread-safety. * Codebase: updated todo.txt. * utils: implement utilsParseGitHubReleaseJsonData(), utilsFreeGitHubReleaseJsonData(), utilsGetApplicationUpdatedState() and utilsGetApplicationUpdatedState(). * utils: add extra logic to move the application's NRO to its proper path if the launch path isn't the right one (commented out at this moment). * utils: add extra logic to replace the application's NRO at exit (commented out at this moment). * defines: add DEVOPTAB_SDMC_DEVICE and tweak GitHub URL macros. * DownloadTask: set percentage to 0 if the download size is unknown. * DownloadTask: fix ETA string formatting. * OptionsTab: repurpose OptionsTabUpdateFileDialogContent into OptionsTabUpdateProgress. * OptionsTab: implement OptionsTabUpdateApplicationFrame. * RootView: move date formatting into the static GetFormattedDateString() method. * Makefile: use _GNU_SOURCE as part of CFLAGS to use strptime().
