Adrien Destugues 33eead339b * Improve the test for TimeFormat (style and error checking)
* Fix the TimeFormat API, there was a double free. Make it work as expected : you send it a number of seconds and it will format it properly in days, hours, minutes, seconds with proper plural.
 * Cleanup other parts of the Format API from useless things. They may get reintroduced later if we feel the need to do so.
 * AboutSystem now use TimeFormat to display the uptime in properly localized way.
