I wasn't able to work all of Mitchs changes into my repo yet, so from that point my repo is kinda outdated. Though mine has some changes to IzNo's async MySQL, which might be just easier to pull/cherry-pick into Mitchs repoand reverting the free_slot()-bug(sorry, I just interpreted commit message wrong).
Always wanted to address this git incompatibility stuff with some tutorial/video or so, but just lacking motivation in last time. ^^
