Devlog 12

This is a smaller update.

1. I added tooltips to desktop app icons (text that shows up when you hover over the icons).
2. I updated the header on apps so you can now drag the apps around easier.
3. I fixed some bugs and changed some styling, like changing Hacking terminal’s name to HackCMD (I also changed the icon).
4. I added a normal terminal (inspired by @Makkonen ‘s LuckyOS terminal, go check his projects out!). It’s not finished, but you can type “help” to see all currently available commands!
