Files in assets/img/slotitem have different resolutions

The following PNGs are 45x45 rather than 54x54 used by other similarly-functioned images, making them scaling larger than they should: 102/106/107/108/110/111/115/119

I've actually detected this when writing my own program(github.com/ibicdlcod/GuoMuoRuoProject). As currently there isn't a way for other people to run it here is a screenshot:

As you can see the radar icon is much larger than the sonar's, because smaller images scales larger when the size of destination is fixed.
