Post #3434498

I added a few tests (yes, it didn't have any until now). It's mostly fairly small things, but most of the app is out of reach either way - we have no infra for testing UIs. So it will be mostly parser tests, and for now I'm testing a few math utilities, a function that formats timespans, and a function that turns filenames into game titles. Speaking of the last one, I also fixed a few things. It's fairly common to have ROMs prefixed by numbers - e.g. 0028 - Kirby - Canvas Curse (USA).nds. This filename would previously result in "0028 - Kirby - Canvas Curse" as the title, and now it's just "Kirby - Canvas Curse" instead. And there's a test for it as well, yes. This is complicated by the fact a bunch of games actually have 4-digit numbers and a dash as part of their title: 1869 - Erlebte Geschichte Teil I 1941 - Counter Attack 1943 - The Battle of Midway 1943 - The Battle of Valhalla 1943 - One Year After 1985 - The Day After 1994 - Ten Years After 1999 - Hore, Mitakotoka! Seikimatsu 2010 - Street Fighter 2010 - The Graphic Action Game I had to add special cases for these (and a test too, yes). For everything else though - no more numbers.
