Merge pull request #53 from oneandonlydean/feat/userservice-profile

feat(userservice): user name, user number and accessibility settings of the initial user
They report the initial user, following `sceUserServiceGetGamePresets`:
- **Name:** `Player`. A buffer shorter than 17 bytes returns `SCE_USER_SERVICE_ERROR_BUFFER_TOO_SHORT` (`0x8096000A`).
- **User number:** 1.
- **Accessibility settings:** 0, the setting-off value on a fresh console.
