Changed ID_LANG_EVENT_UPDATE_SYS_LANG to USE_EVENT_UPDATE_SYS_LANG
Implemented Sys_ReLaunch in two ways: Using exec (which is disabled since it doesn't work as of 10.2), and displaying a dialog to the user informing them about what they need to do to relaunch the app (um, relaunch the app...).
Fixed potential issue where Sys_Sleep's nanosec count wraps by converting its multiple to a unsigned long long.
Fixed issue where command line arguments included calling app, which it shouldn't have.
Low battery warning isn't removed unless it's set (as opposed to every update changing the value)
