option to install nro from fs, swap LR display, load translations locally, fix scrolling sound, add file name to rename swkdb

- reduce nxlink svcsleep to reduce latency between polling.
- translations can now be loaded from /config/sphaira/i18n/name.json, this is to help aid those creating translations.
- swap LR position in display. the fix is a hack, but it'll do for now.
- sound effects are now consistent throught the app.
- renaming a file will now show the current file name in swkbd, makes it easier to rename from config.ini.template -> config.ini
- removed some dead code that was unused.
- add credits to the readme.
- speed up playlog ini parsing by browsing the ini rather that doing a query for each entry.
