Usability improvements

As I won’t be able to finish the AHCI driver, I decided to improve the usability. I added dbg/dbgclr commands to allow easier debugging by only printing specific debug messages. The CLI got some big improvements, it will now detect commands even with trailing spaces. the loglevel command was renamed to logl for faster typing. Both logl and dbg accept their input now as CLI arguments instead of asking the user themselves.

Roadmap

After stardance I will probably take a little break, but then I want to continue on the AHCI driver, so that I finally can read files from SATA drives! And even after that, there are many more things to explore, like ELF loading, USB, Networking…
